What is the somatosensory homunculus? Which body region would be larger in the homunculus, the face or the hips? Why?
What will be an ideal response
The somatosensory homunculus is a body map depicting the relative amount and location of cortical tissue devoted to sensory reception for each body structure. The amount of sensory cortex devoted to a particular body region is related to that region's sensitivity (that is, how many receptors it has), not its size. The face (especially the lips) and fingertips are the most sensitive body areas, so these regions are the largest part of the homunculus.
