Describe the topographic organization of the somatosensory cortex.
What will be an ideal response?
The cells that respond to sensation from a particular body part are organized as a map of the body surface. Thus, cortex cells that respond to sensation from the elbow are located near cells that respond to sensation from the proximal forearm. Furthermore, the number of cortex cells devoted to a sensation is proportional to the sensitivity of that part–there are many more cells for sensation from fingers and lips than from the back or thighs.
