what lobe part of the brain controls primary somatosensory
The Primary Somatosensory Cortex. Parts of the cerebral cortex in the parietal lobe are involved with processing information related to touch. One such area is the primary somatosensory cortex which is located behind the central sulcus.Neurons in the primary somatosensory are activated when the skin is touched.However, the body is NOT represented in the cortex in proportion to the amount of skin. A map of the human somatosensory cortex was drawn by Dr. Wilder Penfield, a neurosurgeon, in the 1950s.eurons in the primary somatosensory are activated when the skin is touched.
