The somatosensory cortex is located in which brain lobe?

• A. Frontal Lobe
• B. Temporal Lobe
• C. Parietal Lobe
• D. Occipital Lobe

Answer: (D)

The somatosensory cortex is located in the parietal lobe, on the postcentral gyrus just behind the central sulcus. It receives tactile and proprioceptive information from the opposite side of the body via the thalamus and processes sensations such as touch, temperature, pain, and body position. This area is organized somatotopically, meaning different body parts map to specific cortical regions, with more cortical area devoted to highly sensitive regions like the lips and fingertips.

To put it in context, the occipital lobe handles vision, the temporal lobe processes auditory information (and memory), and the frontal lobe contains the primary motor cortex and regions involved in planning and decision-making. The somatosensory cortex sits in the parietal lobe as the main hub for processing tactile and proprioceptive input.
