Somatotopic arrangement

Somatotopy[a] is the point-for-point correspondence of an area of the body to a specific point on the central nervous system.

Areas such as the appendages, digits, penis,[2] and face can draw their sensory locations upon the somatosensory cortex.

[citation needed] Macaques, a kind of monkey, already exhibit somatotopy in their somatosensory and motor systems at birth.

[3] Functional magnetic resonance imaging (fMRI) was employed to determine areas of activation in the cerebellar cortex in humans during a series of motor tasks.

The activation areas for movements of lips, tongue, hands, and feet were determined and found to be sharply confined to lobules and sublobules and their sagittal zones in the rostral and caudal spinocerebellar cortex.
