Visual discrimination in monkey with removal of inferotemporal cortex.
The monkey with removal of the inferotemporal cortex (IT monkey) showed a marked impairment of discrimination between a pair of visual pattern stimuli, which consisted of different patterns on the identical background [corrected] plaques. The present study showed that an IT monkey, unlike an unoperated normal monkey, performed discrimination with utilizing a partial cue within the whole configuration of pattern stimuli. In contrast to a general concept, the present finding appears to raise a question as to whether the IT monkey can perceive or identify visual pattern.
