Final answer:
After hand amputation, the area of the body that might accidentally convey sensory information from the missing hand is the face.
Step-by-step explanation:
Based on the concept of somatotopy, after having your hand amputated, the area of your body that might accidentally convey sensory information from your missing hand is the face.
In the brain's cortex, there is a map of the body called the sensory homunculus. This map is not proportional to actual space. Sensitive parts like the face and fingers are represented by more areas than less sensitive parts like the legs or back.
Since the face is highly sensitive to touch and has a greater representation in the somatosensory cortex, sensory information from the missing hand may accidentally be interpreted by the facial representation in the brain.
