CONTRIBUTIONS OF NOCIRESPONSIVE AREA 3A TO NORMAL AND ABNORMAL SOMATOSENSORY PERCEPTION

Somatosensory cortex in the postcentral gyrus of humans and other primates comprises four cytoarchitectonically, connectionally, and physiologically distinct cortical areas – Brodmann areas 3a, 3b, 1, and 2 (Figure 1AB). Each of these areas forms a long strip running along the central sulcus from the midline to the lateral fissure. The most anterior of these areas, area 3a, lies in the fundus of the central sulcus, flanked anteriorly by motor cortical area 4 and posteriorly by somatosensory area 3b.
