Document Summary
Striate cortex: another name for visual cortex due to its striped appearance, aka same things as v1 (pvc, striate cortex = v1 = pvc. The blobs do different things than the interblobs: blobs are sensitive to color, interblobs: capture orientation information and send it to extrastriate cortex for processing of information. In area v2: have thin / thick stripes: thin stripes: capture information about color perception (capture info from blobs and pass it forward, thick stripes: capture information about motion information. Therefore, colour vision: primary job of v4, but distributed throughout occipital cortex, also plays a role in detection of movement, depth, and position. Primary visual cortex (v1: receives input from lgn, output to all other levels (extrastriate areas) Secondary visual cortex (v2: output to all other levels. Dorsal stream: visual guidance of movements, where" pathway. Ventral stream: object perception, what" pathwayi.
