Phantom limb syndrome is a condition in which patients who have lost a body part, for example a limb, experience sensation in the missing limb. This condition appears to be due to reorganization and rewiring in the brain so that sensations are localized to the missing body part. Which part of the brain is most likely being reorganized?
A) medulla
B) primary somatosensory cortex
C) somatosensory association area
D) primary motor cortex

The primary somatosensory cortex is responsible for processing information about touch, pain, temperature, and proprioception (awareness of body position). It receives input from sensory neurons in the body and creates a map of the body’s surface on the cortex. In phantom limb syndrome, the area of the somatosensory cortex that corresponds to the missing limb is rewired to respond to input from nearby areas, leading to sensations in the missing limb.
