somatotopic organization

Somatotopic organization refers to how different parts of the body are mapped onto specific areas of the brain and spinal cord. This means that nearby parts of your body are represented close to each other in the brain’s sensory and motor regions. For example, the hand and fingers have dedicated areas close together, while the toes occupy a different region. This organized layout helps the nervous system efficiently process sensory information and control movement, ensuring that signals from specific body parts are routed to precise brain regions for interpretation and action.
