Abstract
Through a series of complex transformations, the pixel-like input to the retina is converted into rich visual perceptions that constitute an integral part of visual recognition. Multiple visual problems arise due to damage or developmental abnormalities in the cortex of the brain. Here, we provide an overview of how visual information is processed along the ventral visual cortex in the human brain. We discuss how neurophysiological recordings in macaque monkeys and in humans can help us understand the computations performed by visual cortex.

Edge detection is thought to mimic one of the initial steps in processing visual information in primary visual cortex (2 , 79 , 136 ). Original photo taken by Nambi Nallasamy.
