(Redirected from Post central gyrus)
Region of the parietal lobe of the brain
Postcentral gyrus
Postcentral gyrus of the human brain
Brodmann areas 3, 1, and 2 of human brain. Brodmann area 3 is in red, area 1 in green, and area 2 in yellow.
The primary somatosensory cortex was initially defined from surface stimulation studies of Wilder Penfield, and parallel surface potential studies of Bard, Woolsey, and Marshall. Although initially defined to be roughly the same as Brodmann areas3, 1, and 2, more recent work by Kaas has suggested that for homogeny with other sensory fields only area 3 should be referred to as "primary somatosensory cortex", as it receives the bulk of the thalamocortical projections from the sensory input fields.
