Document Summary

The visual cortex has a topographic organization (fovea is over represented and the periphery is under represented: what pathway temporal cortex, object recognition, where pathway parietal cortex, represents spatial information and coordinates vision with action. Information is encoded by the ganglion cells that are then combined by higher visual processes to form various features (kuffler: on-off ganglion cells. Firing rate increases when light hits the center of the cells receptive field in the retina. If light hits just around the center the rate of firing will decrease. Depth and surface perception information laid out on the retina is 2d but we need to perceive a 3d version of the world. Visual pattern recognition: how do we recognize the identity of letters, 1. Evidence for the theory if letters have many features in common (i. e. c and g) people are prone to confuse them.
