Brain has inferior temporal cortex region {inferotemporal cortex}| (IT) [DiCarlo and Maunsell, 2000] [Gross, 1998] [Gross, 2002] [Logothetis and Sheinberg, 1996] [Tamura and Tanaka, 2001] [Tanaka, 1996] [Tanaka, 1997] [Tanaka, 2003] [Tsunoda et al., 2001] [Wang et al., 1996] [Young and Yamane, 1992].
functions
IT affects visual recognition by visual cortex. IT analyzes complex visual stimuli and discriminates visual forms. IT is for attention and visual memory. IT selects object to view.
IT responds best to new stimuli. If new visual feature matches the original, brain suppresses half of inferotemporal neurons activated by visual feature. One-third of inferotemporal neurons decrease response to familiar or repeated stimuli.
Some inferotemporal neurons recognize individual faces at different views, face prototypes, or poses, ignoring brightness.
Some inferotemporal neurons respond to stimulus actively held in memory and receive back projections from prefrontal cortex [Miyashita et al., 1996] [Naya et al., 2001] [Sheinberg and Logothetis, 2001].
input
IT receives from dorsolateral visual area.
output
IT sends to object recognition centers and attention and orientation systems.
damage
Inferior temporal lobe damage causes inability to categorize or discriminate.
