Somatotopic arrangement

Somatotopic arrangement is the maintenance of spatial organisation within the central nervous system. For example, sensory information maintains its structure (i.e. sensory information on the hand remains next to sensory information on the arm) throughout the spinal cord and brain.Densely innervated areas of the body occupy large regions of the cortex.
