The greater the sensitivity of a part of the body, the larger the area of somatosensory cortex associated with it. This is because the somatosensory cortex is responsible for processing sensory information from different body parts, and the more sensitive a body part is, the more neural receptors it has and the more information it can transmit to the brain. As a result, the somatosensory cortex dedicates more area to processing information from these sensitive body parts, leading to larger representations.
