so·mat·ic sen·so·ry cor·tex, somatosensory cortex
the region of the cerebral cortex receiving the somatic sensory radiation from the ventrobasal nucleus of the thalamus; it represents the primary cortical processing mechanism for sensory information originating at the body surfaces (touch) and in deeper tissues such as muscle, tendons, and joint capsules (position sense); it corresponds approximately to Brodmann areas 1, 2, and 3 on the postcentral gyrus and the posterior paracentral gyrus.
Synonym(s): somesthetic area
The region in the parietal lobe of the cerebral cortex in which lie the terminations of the axons of general sensory conduction pathways. This area feels and interprets the cutaneous senses and conscious proprioceptive sense.
