(n.d.). Occipital Lobes. Retrieved January 11, 2015, from http://biology.about.com/od/anatomy/p/occipital-lobes.htm Directionally, the occipital lobes are posterior to the temporal lobes and inferior to the parietal lobes. -The primary visual cortex at the very back of the occipital lobe is most comonly called V1 which receives input from the optic tract. The various parts of the occipital lobe are labeled with a V (for visual) followed by a number. The various parts of the occipital lobe are labeled with a V (for visual) followed by a number. -V2 surrounds V1 and it's funtion is to repeat what V1 does, but it also detects contours and the distinction between figure and ground. -V3 (above V2), gets inputs from both V1 and V2 and specializes in depth, distance, and global motion. -V4 (under V2) specializes in more complex perception of specific objects. -V5 (also known as MT which is further toward the front of the lobe) processes complex motion Two Pathways -"where?" path: (V1 to V2 to V3 and V5) interprets location and motion in space.-"what?" path: (V1 to V2 to V4) determines the identity of an object Boeree, D.
