somatosensory homunculus

The somatosensory homunculus is a visual map of how our brain perceives touch and sensation from different parts of our body. It shows that areas like the hands, lips, and face have a larger representation in the brain because they are more sensitive and require finer touch discrimination. This mapped area is located in the somatosensory cortex of the brain's brain, specifically in the parietal lobe. The size of each body part on the homunculus reflects the amount of neural resources dedicated to sensing that region, highlighting the importance of touch and sensation in different body parts.
