Neuropsychological basis of pattern vision in macaque monkeys

The central mechanisms of underlying pattern vision in macaques (rhesus and Japanese monkeys) were investigated behaviorally and electrophysiologically. A series of studies indicated that there are two major processes underlying pattern vision. One of two processes is the process of attending selectively to pattern cues at background, with which inferior parietal cortex is concerned predominantly. The other is the process of pattern perception and cognition, in which inferotemporal cortex is involved closely.
