Which brain region is described as responsible for perception of pain?

• A. Prefrontal cortex
• B. Parietal lobe
• C. Occipital lobe
• D. Temporal lobe

Answer: (A)

Pain perception is grounded in the parietal lobe, specifically the primary somatosensory cortex. This region maps sensory input from the body and encodes where the pain is, how intense it feels, and its quality. That sensory-discriminative aspect is the core of perceiving pain. The prefrontal cortex, while important for higher-order processing—like evaluating, planning, and modulating pain through cognitive strategies and expectations—does not establish the basic sensory perception of pain. The occipital lobe handles vision, and the temporal lobe processes auditory information and memory. So, for the sensation of where and how much pain is felt, the parietal lobe is the key region.
