Medical Definition of Secondary sensory cortex
1. A cortical region occupying the parietal operculum (upper lip of the lateral sulcus) closely posterior to the foot of the postcentral gyrus; like the primary somatic-sensory cortex of the postcentral gyrus, this region receives sensory impulses originating in face, trunk, and limbs; projections to the s.s.c. Are from the ventral basal complex (ventral posteromedial and posterolateral thalamic nuclei) and from the primary somesthetic cortex. (05 Mar 2000)
