WebbIn neuroanatomy, the primary somatosensory cortex is located in the postcentral gyrus of the brain's parietal lobe, and is part of the somatosensory system. It was initially defined from surface stimulation … WebbThe activation of SOM-INs in non-sensory cortical areas can modulate intracortical long-range projections and affect signal processing circuits in primary sensory cortices. For example, the optogenetic activation of orbitofrontal cortex projection to V1 reduces the amplitude of responses via recruitment of local SOM-INs [ 87 ]. did harry chapin die
