WebArea 22 is the primary auditory cortex, and it is followed by area 23, which further processes auditory information. Area 4 is the primary motor cortex in the precentral gyrus, whereas area 6 is the premotor cortex. These areas suggest some specialization within the cortex for functional processing, both in sensory and motor regions.
Web2 days ago · A key function of the mammalian neocortex is to process sensory data in the context of current and past stimuli.
