Primate Vision Puts Pieces Together

More than a million nerve cells in each primate retina collect information in the form of light and transmit that information as signals to the brain. Each of these retinal ganglion cells views just a small corner of the world, called the receptive field, as if gazing out of a tiny airplane window."

"In the new study, the team looked at hundreds of cells simultaneously to see how the retina’s cells work together. The researchers found that the irregularly shaped receptive fields of individual nerve cells nestled together perfectly, like a massive jigsaw puzzle."
