Which brain region receives and processes sensory information from the skin and body?

• A. Primary Sensory Cortex
• B. Primary Motor Cortex
• C. Occipital Lobe
• D. Temporal Lobe

Answer: (A)

The primary sensory cortex processes sensory information from the skin and body. Located in the postcentral gyrus of the parietal lobe, it receives signals from the thalamus and analyzes touch, temperature, pain, and proprioception. Its somatotopic map—often described as a sensory homunculus—means different body parts are represented in specific cortical areas, allowing precise localization and discrimination of sensations. In contrast, the motor cortex controls voluntary movement, the occipital lobe handles visual information, and the temporal lobe processes auditory information and memory.
