Brodmann's area 3

Sensory cortical area in the posterior bank of the central sulcus (postcentral gyrus); this area is a principal component of the primary somatosensory cortex. Area 3 is further subdivided into area 3a, which receives proprioceptive signals that originate in deep receptors, and area 3b, which receives discriminitive mechanosensory signals that arise from cutaneous receptors.
