Humans have more sophisticated brains than Primates because of chemicals

Evolution of cognition might be down to brain chemistry”, Andy Coghlan reports, (New Scientist, 28 March 2011):

Philipp Khaitovich of the Partner Institute for Computational Biology in Shanghai, China, and colleagues analysed brain tissue from deceased humans, chimpanzees and rhesus macaques to study the concentrations of 100 chemicals linked with metabolism.

In the human prefrontal cortex, the levels of 24 of these were drastically different from levels in the corresponding brain regions of the other primates. In the cerebellum, however, there were far fewer differences between humans and the other animals, with just six chemicals showing different concentrations.

This suggests that, since our lineage split off from other primates, the evolution of metabolism in the thinking and learning parts of our brains has gone much further than in our “primitive” cerebellum.

I wonder if “‘primitive’ cerebellum” will go the way of “junk” DNA?

The authors may think (they don’t say so directly) that differing brain chemistry is a cause of higher order thinking. It could just as easily be interpreted as a platform for higher order thinking, or even as a consequence of it.
Excerpt: If the error structures of the archaic DNA and one of the modern human DNA samples are similar to each other for one of many reasons, the ABBA-BABA test could report admixture when it did not in fact occur. Even a very small proportion of shared errors could cause a strong effect on the ABBA-BABA statistic. For example, small effects that we typically tend to ignore, such as shared contamination of reagents between the samples, could cause artifactual evidence of admixture.

In this podcast Dr. Patricia Fanning examines the evolutionary claim that humans evolved more sophisticated brains as a result of chemicals other primates did not have.

Human and Non-Human primate aging follows similar patterns.

Source: Iowa State University


Newswise — AMES, Iowa - A recent study debunks the long-held belief in the scientific community that humans have an aging advantage over other primates.

By studying mortality models of human aging along with examining seven wild primate species, researchers have shown that human and non-human primate aging follows similar patterns.

Anne Bronikowski, associate professor of ecology, evolution and organismal biology at Iowa State University, was the demographer for the research team and thinks there are several important findings in the paper, which is published in the current issue of the journal Science.
Life span patterns are most affected by both early adult mortality rates of a species and also how quickly that species increases mortality with advancing adult age.
Humans had been believed to be different from other primates in the measure of how mortality increases with advancing adult age, but this research shows that is not the case.

"First, we found that the thing that makes humans exceptional - that gives them their long life - is that they have both low early adult mortality rate and a low rate of aging," said Bronikowski.

However, some primates in the study aged as slowly as humans, while others had low mortality rates similar to human mortality. So humans were not unique in either measure.

No primates, except for humans, had both. That is what makes us long-lived, she said.

Senescence patterns, or adult aging, can be affected by the environment. The right conditions can make for longer life and these leave their mark on mortality rates.

"Some of these aspects of aging can be molded by local hazards and medical intervention" she added. "Yet, what determines maximum life span for humans remains unknown."

That current maximum life span for humans is 125 years. Life expectancy for Westernized humans is 80-plus years for those who reach puberty, she said. That is an increase from around a 40 to 50-year life expectancy when humans lived as hunters and gatherers.

Since environment and medicine can impact lifespan and aging, the hope is that humans may be able to live healthy lives that are free from the physical deterioration associated with advancing age until close to age of death, Bronikowski said. Comparative studies of different primate species can help us understand where researchers might see evolutionary constraints in aging and where to apply resources for effective treatments.

Bronikowski also noted that females in all species but one lived longer than males. The species that did not have this sex difference in aging and life span, muriqui, is revealing to researchers because it is the only species in the study that does not have a male-male competition for female mates.

The researchers looked at sifaka, northern muriqui, capuchin, yellow baboons, blue monkeys, chimpanzees and gorillas in the study.

As demographer on the project, Bronikowski worked with long-term census data from each primatologist's field study to develop mortality tables and fit models of increasing mortality.

The research results were part of a three-year collaboration through the National Science Foundation's National Evolutionary Synthesis Center and National Center for Ecological Analysis and Synthesis.

Along with Bronikowski, other researchers included Susan Alberts, Anne Pusey and William Morris, all from Duke University, Durham, N.C.; Marina Cords, Columbia University, New York; Jeanne Altmann, Princeton University, N.J.; Dianne Brockman, University of North Carolina, Charlotte; Linda Fedigan, University of Calgary, Canada; Tara Stoinski, The Dian Fossey Gorilla Fund International; and Karen Strier, University of Wisconsin-Madison.

Rare Blonde Capuchin Monkeys slap and then insert sticks to get termites

Blond capuchin monkeys of the Brazilian forests use a special technique — smack, swirl, eat — as they fished termites out of trees, a new study of the critically endangered primates shows.











Blond Capuchins live in the forests of Brazil, but only about 180 are left in the wild. Antonio Souto's group discovered that they use a special technique-and-tool combo to fish termites from their nests in the trees.

"In some observations we have seen them do this fantastic behavior, fishing for termites," said Antonio Souto of the Universidade Federal de Pernambuco in Brazil. Similar insect-fishing behavior has been seen before, but the technique used by the blond capuchins is unique, he said.
There are only 180 of the capuchins left in the wild. The research team monitored a group of six of them as it moved through the trees and noticed that three of the four adult males in the group would climb up to a termite nest and start hitting it with their hands.

Each monkey grabbed a branch off the tree and poked it into the nest, using a rotational insertion technique to gain entry. They pulled out their sticks and inspected them, then ate the termites on them. Still holding the sticks, the monkeys tapped the nest again with their left hands and repeated the procedure.

To see how effective this technique was, the researchers gave it a try themselves. They climbed up ladders to the termite nest and copied the monkeys' movements.

"It really worked. The way they do it really enhanced their catch," Souto told LiveScience. "I think they can do better than we did; they have more experience."

While the whacking and the use of the stick seemed to increase their take-home, the rotational movement didn't. Instead, the researchers discovered, that twisting prevented the stick from breaking, allowing the monkeys to reuse it. "In the beginning we saw how difficult it was to perforate the nest wall without rotating the sticks," said Souto. "This has an effect on the life span of the stick."

The researchers are currently sifting through other data they collected while monitoring the monkeys, including on the animals' foraging behaviors. They plan to follow a separate, larger group of capuchins to determine if it fishes for termites the same way.

Souto said, "It's possible that the technique is unique to this small group of animals."
The study is published in today's (March 8) issue of the journal Biology Letters.

Snow Macaques find sanctuary in the hot springs

Nagano, Japan (CNN) -- In an outdoor natural hot spring, or onsen, in snow-covered Nagano, Japan, people get a rare up-close view of snow monkeys in their natural habitat.

The monkeys mostly ignore the tourists armed with their cameras and the scientists who've traveled hours to be within centimeters of the crimson-faced creatures.

For 46 years, the Jigokudani Monkey Park has been a sanctuary for these snow monkeys. The monkeys lounge, appearing to almost nod off in the steaming hot bath, almost all of them with hot water up to their shoulders.

"It's pretty incredible," says Kate Bokan-Smith, an American from California teaching English in Japan for a year. "At first, it's a little frightening. But it's special that the monkeys can eat their food, be here without being pestered by humans. And yet we can be this close. I think it's special."

Vince Manna, a nature photographer who has taken pictures of 200 species of monkeys in the Amazon, Africa and Southeast Asia, agreed. He's never seen anything like this sanctuary, he says, as he points his high powered camera lens towards the steaming onsen teeming with monkeys. "This is unique."

Jigokudani Monkey Park's beginnings were borne out of man's frustrations with the snow monkeys, whom Nagano residents considered pests. As Nagano grew deeper into the hills, the monkeys grew less wary of the human invaders. Monkeys regularly broke into shops and homes to steal food, even as people sat nearby, the park said.

Residents had considered culling the animals, who grew emboldened by the year. But the park owners noticed an unusual habit forming among the monkeys: They appeared to enjoy Nagano's main tourist attraction, the outdoor onsens.

The park decided to build a giant outdoor hot spring away from the town and deep in the mountains. Jigokudani Monkey Park also began regular feedings. These incentives drew many monkeys away from Nagano, although to this day, they still wander the town.

Nagano residents have since shifted their feelings toward the monkeys, as tourists started going to the monkey onsen.

French, English and Chinese are just a few of the languages being uttered around the onsen. "It's magical, fabulous!" said Christine Cocks, from Australia. "They're just so cute. You could stand and watch them all day."

Her family member, Jessiah, echoed the sentiments, calling the relationship between the town and the monkeys "symbiotic."

In the freezing snow with little human shelter, the tourists can only really stay for minutes. They'll head back to Nagano and spend money in the restaurants and hotels and talk about the magical monkeys in the hills.

Helping Hands Monkey Fullfills a Young man's life

CONCORD (CBS) — “As long as he had a ball and bat in his hand he was a happy kid.” Ellen Rogers talks about her son Ned Sullivan, who five years ago was just like any other college senior.

But that’s when life, just stopped.
“It’s that call every parent dreads,” recalls Ellen.

Ned had a seizure behind the wheel and crashed into a brick wall and broke his neck. He was paralyzed from the neck down. He spent a long year in the hospital getting better, but when he got home, he got worse.

Ned says, “I always felt alone and stuck and depressed.”

But then his sister was invited to a school assembly and the topic? Helping Hands Helper Monkeys. The organization helps people with spinal cord injuries by giving them monkey to help with everyday tasks.

Obese Monkeys are more prone to stillbirths

Obese pregnant macaques tend to have damaged placentas and are prone to stillbirth. If the same is true for people, it could explain why women in high-income countries who are obese before they conceive are twice as likely to deliver a stillborn child compared with lean women.
Some have argued that obese women are more likely to have stillbirths because their extra fat makes ultrasound scans less accurate, leaving more problems unnoticed. Anne Evans at Oregon Health & Science University in Portland and colleagues suspected the problem might be more fundamental. So they studied what happened to obese Japanese macaques during pregnancy.

They began by feeding 15 female macaques a high-fat diet and nine others a standard "monkey chow" diet. Nine of the macaques on the high-fat diet became obese with insulin resistance, while six remained at a relatively healthy weight.
The team then mated the macaques over several seasons. After 120 days into each pregnancy they measured blood flow into the uterus and placenta – the organ that connects the fetus to the uterine wall and provides it with nutrition.

Blood flow to the uterus was 38 to 56 per cent lower in all the macaques on a high-fat diet compared with the healthy-eating animals. Blood flow to the placenta itself, meanwhile, was 32 per cent lower in obese monkeys than in those on the balanced diet. Samples of placental tissue from obese animals also showed signs of damage.

Stillbirth risk

Ten days later, the monkeys' infants were delivered by caesarean section. Among the obese mothers, seven out of 20 pregnancies were stillborn, compared with only one stillbirth from 26 pregnancies in the healthy diet group, and one in 13 pregnancies from the macaques who maintained a healthy weight, despite the high-fat diet.

According to Evans, poor nutrition can probably damage the placenta, given that high-fat diets, regardless of subsequent obesity, lowered blood flow to the uterus in the monkeys. Subsequently, "maternal obesity and insulin resistance further exacerbates placental dysfunction" resulting in more stillbirths, she says.

David Ellwood, an obstetrician at the Australian National University in Canberra, agrees that "placental dysfunction is the most likely explanation" for the increased risk of stillbirths amongst obese mothers.

He speculates that high-fat diets may increase the fat content of placental tissue, which could block blood flow and so limit nutrition to the fetus.

What do monkeys see when they look into a mirror?

In the popular children’s series, the mischievous monkey Curious George loves to look at himself in the mirror. But do his real-life cousins have the same hobby? Scientific consensus has long been that rhesus monkeys see the monkey in the mirror as a new playmate, not a reflection of their own image. Recent research, however, suggests that monkeys might really be as probing and self-aware as readers of the Curious George books were led to believe.

In 2010, Abigail Rajala, a neuroscience graduate student at the University of Wisconsin-Madison, noticed that rhesus monkeys in the lab seemed to recognize themselves in mirrors, grabbing them and manipulating the mirrors to see their reflected image. When she told lab director Luis Populin of her observations, they worked together to develop an experiment to determine what the monkeys were perceiving, using an adaptation of the “mark test.”

The test, designed to experimentally measure self-awareness in animals, involves a small mark (a dot of dye or a sticker) placed on a sleeping animal’s forehead and ear, both places that an animal can’t normally see. The animal is then woken and placed before a mirror.

Scientists think that what the animal does next reveals whether or not it is self-aware. If the animal touches the marks on its own body and not on the reflection, then it is aware of its embodied self, according to those scientists who endorse the test. Chimpanzees, one of our closest primate relatives, have passed the test. Rhesus monkeys, however, have failed it since the 1960s, when the mark test was developed.

In their experiment, Populin and his team placed full-length mirrors within reach of the monkeys, so they could move them. Surprisingly, the monkeys reacted to the mirrors, using them to touch their genitals and the medical implants on their heads, both of which are not normally seen without the aid of a mirror and aren’t usually examined. From this, Populin concluded that the monkeys recognized themselves in the mirrors. He and Rajala published their results on September 29 in the journal PLoS ONE.

But not everyone agrees that the rhesus monkeys knew they were looking at their own mirror images. “I think there’s better evidence for recognition in magpies than in these monkeys,” says Daniel Povinelli, a primatologist at the University of Louisiana-Lafayette.

Magpies pass the mark test with flying colors; they recognize and pick at stickers placed on their bodies. Povinelli believes that rhesus monkeys, in contrast, are simply engaging in normal behaviors like grooming and attempting to socialize with the mirror monkeys. He also maintains that the monkeys have not passed the mark test because they still have not recognized a traditional mark of dye or a sticker.

But Populin counters that it’s a matter of having a “salient mark”—a mark interesting enough for a monkey to notice in its reflection. Monkeys find the implants to be more interesting than traditional marks, he believes. Populin hopes to conduct further studies with the rhesus monkeys, using them to examine human conditions like gaze aversion, in which one person avoids eye contact with another, even during a conversation.
The argument over whether monkeys really recognize their mirror images is not just a narrow debate among primatologists. It also has broad implications for evolutionary theory. “There is a huge ideological clash in the field of cognitive evolution,” explains psychologist Phillipe Rochat of Emory University in Georgia, who has researched mirrors and their role in the human psyche. The clash is over how self-awareness evolved: either as a distinct evolutionary jump, or as something that evolved gradually and continuously along the evolutionary ladder. The ability of monkeys to recognize themselves in a mirror might indicate a level of self-awareness that supports the idea of a gradual development of that ability along the evolutionary tree.

Rochat added a caveat, saying that while we may think we know what is going on in an animal’s head during a mark test, we do not know for sure, in part because human interpretations are biased by our own perceptions of self in a mirror. “We see not just ourselves, but what we project to the outside world,” Rochat says. “There is no other animal that shows such a compulsive propensity to self-present.”

Spider Monkeys and Woolly Monkeys Frolic with each other

Anthony Di Fiore, a primate biologist at New York University, writes from Ecuador, where he is using GPS technology and camera traps to study the behavior of male spider monkeys.

Monday, Jan. 10
Here at the station they are saying that we brought the rain with us. After two virtually bone-dry weeks in late December and early January, it has been alternating between drizzle and full-on downpour since we arrived, punctuated by just a few hours of sun here and there. At night, lying in the cabins, we can hear rain rattling for hours on the corrugated aluminum roofs, drowning out the typical nighttime chorus of frogs and insects.
Despite the rain, it’s been a great three days of monkey follows. We’ve checked in on radio-collared groups of woolly monkeys, sakis and titis. But most of our time has been spent making sure that all of the spider monkeys in our main study group (called MQ-1) are all still around. MQ is our abbreviation for maquisapa, the word in the Indian language Quichua for spider monkey that translates (appropriately!) as “big hand.”
Although spider monkeys live in large social groups, you only rarely see more than a handful of animals at a time traveling or hanging out together. Instead, you run into subgroups consisting of one or few females and their offspring, a set of patrolling males or a male-female consorting pair. Subgroups join together and split apart frequently, leading researchers to describe the pattern as “fission-fusion” sociality. This kind of social system is rare among primates — indeed, it’s rare among mammals generally. A short list of mammals that live in fission-fusion groups would include chimpanzees, muriquis, elephants, some social carnivores and a few cetaceans.

A Long Journey Into the Ecuadorean Forest

.In three days, we’ve already found about half of the individuals in our group, including three of the six adult males and six of 11 adult females. MQ-1 contains about 32 individuals, counting the kids, and occupies a home range of about 600 hectares. Each hectare is 100 meters square, or roughly the equivalent of two American football fields laid next to each other, so this is a huge area to explore. But we’ve become pretty good at thinking like the monkeys over the past few years, so we can narrow our search by focusing on the routes that the monkeys commonly use to travel their range and by checking out the feeding trees that we know they like and that are currently fruiting.

Today, we checked out a huge Clarisia racemosa tree in the heart of the group’s range. Clarisia, from the same family as figs, produces fleshy, scarlet-colored fruits with a single large seed. It’s a favorite of the spider monkeys, which will pick and swallow dozens in a single feeding session. Sure enough, 30 meters up in its spreading crown we found the female Sofia (named after my older daughter), who was the first spider we learned to recognize. Sofia was with her latest two kids, Silvi (a female, born in late 2005 and now an impish adolescent) and Summer (a tiny male, born in the summer of 2009). Also nearby was a large group of woolly monkeys that soon began feeding on the Clarisia, too. With the woollies in the tree, we had to move back to avoid the fusillade of half-eaten strawberry-size fruits raining down from 30-plus meters.

The high point of the morning’s observations came a few minutes later when the feeding frenzy ended and both species of monkeys retired to the surrounding trees to rest and digest. With her mother and brother resting in the crook of a tree above her, Silvi approached and began bouncing around a couple of smaller woolly monkey juveniles. They responded by getting up and following Silvi as she scrambled up some lianas (woody vines), threw herself into the thin crown of a subcanopy tree, and then clambered back to repeat the whole process. It turned into a rare, long bout of interspecies play, with Silvi and the woollies chasing one another back and forth for 15 minutes or so until the woolly group moved off.

Minnie the Capuchin Monkey (Helping Hands) has a companion

The Helping Hands Monkeys are a wonderful addition to a home where they are needed. Remember readers, these are highly trained monkeys by professional people that work with them all of the time. Please do not be disillusioned that if you bought a baby monkey you also could do this training. It won't happen. It's takes full dedication, knowledge and years and years of training.

Story-
Specially-trained Capuchin monkeys in the US are helping physically disabled people with the housework by performing tasks such as removing garbage, fetching the telephone or switching on the microwave. The furry companions are also helping paraplegics cope with loneliness.
It's her small hands that make Minnie especially useful. Hairy and slender, with slim fingers and black nails, the Capuchin monkey's hands are just right for twisting open a bottle of juice or fetching the telephone. And when Craig Cook's head itches, Minnie comes and scratches it until he feels better.

"She is more human than you would think," Cook says. The 44-year-old American, who has been paraplegic for more than 14 years, runs his stiff fingers lovingly through Minnie's fur as she cuddles on his lap, observing his guest curiously with her large, brown eyes. Then the monkey jumps up and crosses the kitchen of Cook's bungalow at a wild run, screeching and leaping, a bundle of energy wrapped up in dark brown fur.

"Pretty amazing, isn't it?" Cook says, his eyes shining. He has shared his bungalow here in La Habra, near Los Angeles, with the 30-year-old Capuchin monkey for the past six years. They watch Los Angeles Angels baseball games on TV together, or enjoy the California sun from the patio. And when Cook has "one of those bad days," it's Minnie who manages to make him laugh.

"It's wonderful to have an animal like that at home," Cook says. A former engineer and American football quarterback, he broke his spine in a car accident. He's very lucky to have Minnie -- there are only 45 Capuchin monkeys like her in the entire US, and Minnie is one of the best.

Monkey School
Minnie spent several years in training at the Monkey College, a facility run by a Boston-based aid organization called Helping Hands. This unusual school trains monkeys as household assistants and life partners for paralyzed people -- with great success. "The Capuchin monkeys provide independence and the gift of joy and companionship to the recipients, says Helping Hands employee Andrea Rothfelder. "These animals are very affectionate and loving; a lot of recipients call it a little miracle when their monkey moves in with them."
Director of training Alison Payne describes the Monkey College as a "mixture of pre-school and zoo." Helping Hands has a total of 180 monkeys, 50 of them currently being trained in Boston. Here in the three-story center, the monkeys practice using light switches, drawers, bottles and CD players. They learn the actions first in a room with only Spartan furnishings; later they practice in a "teaching apartment" outfitted with a wheelchair, bed, bookshelf and kitchenette.

Trainers drill the monkeys on around 30 commands, including "fetch," for retrieving an object, and "trash," for taking something to the garbage can. "Push" might mean the monkey should shut the refrigerator door, while "open" would achieve the opposite. Motivation for learning tasks is provided with peanut butter and spray can whipped cream.

"The monkeys are naturally curious," Payne says. "We try to expand their attention space." Still, the monkeys are also allowed some time off. Today Chichi and Jessica are romping around the playroom, chasing bubbles. For their classmate Tricia, it's bath day. Trainer Jennifer Evans has filled the kitchen sink with a lukewarm bubble bath, where Tricia is splashing about, poking her soaking wet head over the edge. A few minutes later, the trainer comes over to rub her dry.

"They're very much like two-year-olds," Payne says. Actually, the monkeys are between eight and 10, the ideal age range for drilling and training, when they start at the Monkey College. First, they get used to people by living in foster families. Next come two to four years of training. Once they're housetrained, they can move in with a disabled person.

Inseparable Companions

When Cook began his life together with Minnie, the evening that ruined his life was already several years behind him. On January 12, 1996, the engineer met a colleague for dinner in Los Angeles. The two left the restaurant shortly before midnight. "It was a mild evening, and Tyler wanted to take a drive in my convertible," Cook recalls. As they sped down the highway, Cook's colleague lost control of the 300-horsepower car. The vehicle flipped over and slid down an embankment. Cook's spine snapped instantly; his colleague was barely hurt.

Cook lost everything that day -- his job; his girlfriend, who soon moved out; but above all control over his own body. Unable to adjust to his new life, he found himself sliding into depression. But when a friend heard of Helping Hands, Cook contacted the organization and sent an application video. A couple of months later, Minnie entered his life.
"When the trainers came out here, they stayed for about a week," he recalls. "It was only then that she accepted me as the new king." That's the way of Capuchin monkeys -- they live in groups and choose their leaders with care.

Today, Cook and Minnie are inseparable. "Spoon," Cook says and the monkey fetches one from the silverware drawer. "Sun" -- Minnie turns on the light. "Can you do hand?" -- Minnie hoists her master's arm, which has slipped down from the armrest. He uses that hand to operate his wheelchair.
"Minnie can be lifesaving for me," Cook says. One time, his wheelchair got stuck on the patio as the sun was going down. Cook knew he was facing an entire night sitting in the dark, freezing and getting wet, until his caregiver arrived in the morning. He called Minnie, who brought his telephone. An hour later, help was there. "I had tears in my eyes," Cook says.
"The monkeys can be a lifeline; however, the most important thing of all is the companionship that they bring and this unconditional love," says director of training Payne. "Suddenly you have this little monkey person at home who just thinks that you are the coolest thing ever."

'They Alleviate the Pain and the Loneliness'

Helping Hands employees tell the story of a veteran who lost both his legs in Iraq. "He says that the monkey is the only one who takes him the way he is and who doesn't notice that he hasn't any legs," Rothfelder says. The monkeys could never take the place of a full-time caregiver, "but they allieviate both the pain and the loneliness of being home alone and also provide some tasks in the house."

It's hardly surprising that the clever Capuchin monkeys are in hot demand, but Helping Hands is only able to provide between six and eight of the monkeys to paralyzed individuals each year. It costs the organization around $40,000 (€30,500) to train a single monkey, all of which must come from donations. The service is free for the patients.

Craig Cook can count himself lucky -- his Minnie has granted him a new life. He remembers clearly the moment when the monkey jumped onto his shoulder for the first time, after five months together. "Suddenly she rubbed her fingers through the back of my hair," he says. "That's the ultimate sign of affection."

Cook estimates Minnie could live another 15 years, but he's loath to think beyond that point. The monkey won a place in his heart long ago.
"Minnie, are you OK?" -- these are the words he'll use to call the monkey tonight, after the caregiver has helped him into bed. And Minnie will answer him, from her cage in the living room, where she rolls herself up beneath a small, light blue blanket.

"And she will go toot toot toot," Cook says. Then he gives a small smile and explains: "That means, 'Everything is all right.'"

Kasey the Helping Hands Monkey

We all know about service dogs - animals trained to help the visually-impaired, and the physically-challenged. But, those aren't the only service animals out there.

Meet Kasey, one smart monkey.

She was specially trained by the organization, "Helping hands: monkey helpers for the disabled." Kasey puts her skills to work, helping Ned Rogers in everyday living.

Ned is a Concord, Mass. resident who was paralyzed in a car accident when he was 22. He was a senior at the University of Arizona in Tucson. He and Kasey have forged a special bond.

Ned, Kasey, and Kasey's mother's story is told in a new book called, "Kasey to the rescue," written by Ned's mother, Ellen Rogers.

"It's been four years and she just brings light to his day," said his mother.

Kasey was trained to perform simple tasks that help mobility impaired, like putting a CD in a player, and turning on light.

But above all, Ellen Rogers says, "the real thing that she does for him is fill a void of loneliness and isolation that has come from his accident."

New Study Shows Monkeys Can Learn And Apply Mathematical Principles

 
monkey primate math rule brain neuron













Like a lot of humans, monkeys might not be able to do calculus. But a new study shows that they can learn and rapidly apply abstract mathematical principles.

Previous work has shown that monkeys and birds can count, but flexible applications of higher mathematic rules, the study authors asserted, "require the highest degree of internal structuring"—one thought largely to be the domain of only humans.

So researchers based at the Institute of Neurobiology at the University of Tubingen in Germany set out to see whether rhesus monkeys could learn and flexibly apply the greater-than and less-than rule. They tested the monkeys with groups of both ordered and random dots, many of which were novel combinations to ensure that the subjects couldn't have simply memorized them. The monkeys were cued into applying either the greater-than or less-than rule by the amount of time that elapsed between being shown the first and second group of dots.

"The monkeys immediately generalized the greater than and less than rules to numerosities that had not been presented previously," the two researchers, Sylvia Bongard and Andreas Nieder, wrote. "This indicates that they understood this basic mathematical principle irrespective of the absolute numerical value of the sample displays." In other words: "They had learned an abstract mathematical principle."

But the researchers were after more than simple ape arithmetic. "If and how mathematical rules can be represented by single neurons," they wrote, "has remained elusive." So during the experiment, they recorded the activity of randomly selected neurons in the lateral prefrontal cortexes of the rhesus monkeys. They chose that region of the brain because functional imaging (fMRI) studies have shown that rule-based arithmetic activates that part of the brain in humans, too. 

The data revealed that in the observed part of the brain, the majority of the neurons selected were involved in applying the mathematical rules (with equal portions activating for the greater-than and less-than applications) rather than obtaining and retaining the sensory details. The researchers concluded that this begs for a processing model that has "specific 'rule-coding' units that control the flow of information between segregated input, memory and output."

What does this mean for us, the only calculator-punching primates? The researchers noted that it likely points to a much older evolutionary root to abstract math: "These neuronal circuits…could readily be adopted in the course of primate evolution for syntactic processing of numbers in formalized mathematical systems."

The research was published online January 18 in Proceedings of the National Academy of Sciences.

Monkeys Are NOT Pets

Sahabat Alam Malaysia (SAM) refers to a media article on the keeping of primates as pets. It is truly disturbing to see an increasing number of baby monkeys being sold in pet shops.

Licences for their keeping are freely issued by the Wildlife Department for both pig-tailed and long-tailed macaques on grounds that they are abundant everywhere.

Has the department ever considered that an infant monkey will eventually grow up and become the wild animal it was meant to be? Raising a monkey among humans does not change the wild nature of these monkeys and as they mature their natural inclinations are stifled by attempts to mould them in to 'obedient pets'.

In accordance with their natural behavior, they often bite and scratch. The end result is displacement following negligent and abusive treatment both physically and mentally of the monkey by its owners.

Then again, as far as the welfare of primates is concerned, permit holders are never subjected to inspection for proper facilities and care except when there is a complaint from the public. As such many pet monkeys end up either in small cages or on short chain which restrict movement.

Monkeys need large open spaces with natural settings to jump and hang around to keep them challenged and mentally stimulated. They need a large amount of social interaction and attention from the owner apart from commitment of time for routine care. Failure to provide all of these needs will result in severe behaviourial and psychological problems for the captive monkeys.

Problems arise when finding a new home for a pet monkey as the monkey has bonded to its owner. Normally, they will be given to zoos or released in the wild which result in dire consequences for the released pet.

From the health aspect, infections such as dysentery, herpes , hepatitis, scabies and even tuberculosis can be transmitted from primates to humans. Similarly, human carriers may also pass the salmonella bacteria to monkeys directly or indirectly.

The worst part of the trade is the taking of baby monkeys from the forest which is symptomatic of a largely unregulated trade in pet primates – creating problems with everything from smuggling to serious health risks to the public, let alone to the animals. Traders may not be licensed and SAM doubts whether there is proper monitoring of the trade in pet primates.

Again separating the mothers from their babies is an extremely cruel act as the mother mourns, screams and will fight to the death for her infant. One can just question as to how the traders get hold of the babies and this must not be taken lightly by the Wildlife Department.

SAM is strongly opposed to the keeping of a monkey or ape as a pet. We recommend that federal and state legislation prohibit private ownership of non-human primates and future commerce in non- human primates for the pet trade while strongly discouraging the rearing of a monkey or ape as a pet.

Most owners lack the knowledge, devotion and ambition necessary to prevent disease transmission and to maintain the health and welfare of the primate. Therefore, veterinarians should diplomatically discourage the practice of keeping a primate as pet.

Currently, there is no regulation to effectively address this issue and the exotic animal trade raises complex issues of animal welfare, public health, and conservation.

The use of a monkey or ape as a pet should be strongly discouraged. Wild animals deserve to be in their natural habitat, especially non-human primates which come with numerous health and safety risks.
