Damage to which lobe would most affect the sense of touch?

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

Answer: (B)

Touch is processed mainly by the parietal lobe, where the primary somatosensory cortex sits in the postcentral gyrus. This area receives and interprets tactile information such as pressure, texture, temperature, and proprioceptive signals, mapping sensations across the body. When this region is damaged, the brain’s ability to feel and localize contact is disrupted, and sensory information from the opposite side of the body is typically affected due to contralateral representation. The frontal lobe is more about planning, movement, and higher cognitive functions; the temporal lobe handles hearing and memory; and the occipital lobe is primarily for visual processing. These areas aren’t the main hubs for touch, so damage there wouldn’t impair tactile sensation as directly as damage to the parietal lobe.
