The parietal lobe processes which sensation?

• A. Touch
• B. Vision
• C. Balance
• D. Hearing

Answer: (A)

Touch is processed by the parietal lobe because it houses the primary somatosensory cortex in the postcentral gyrus, which receives input from touch receptors and proprioceptors all over the body. This region creates our sense of touch and body position, organized as a sensory map that reflects how different body parts are represented. While the parietal lobe helps with spatial awareness and integrating sensory information, the other sensations come from different brain areas: vision is primarily handled by the occipital lobe, balance by the vestibular system and cerebellum (with some input to parietal regions), and hearing by the temporal lobe. So, the sensation most characteristically associated with the parietal lobe is touch.
