Which brain area registers and processes body sensations?

• A. Frontal Lobe
• B. Occipital Lobe
• C. Somatosensory Cortex
• D. Cerebellum

Answer: (C)

Understanding body sensation begins with the somatosensory system. The primary somatosensory cortex, located in the postcentral gyrus of the parietal lobe, registers and processes touch, temperature, pain, and proprioception. It receives signals from the thalamus and maps sensations in a somatotopic layout, so different body parts occupy distinct cortical areas (more sensitive regions like the hands and lips take larger areas). While the cerebellum helps coordinate movement using sensory input, and the frontal lobe handles planning and higher cognition, these regions do not primarily register bodily sensations. The occipital lobe is dedicated to vision. Therefore, the brain area that registers and processes body sensations is the somatosensory cortex.
