A cortical homunculus (from Latin homunculus 'little man, miniature human' ) is a distorted representation of the human body, based on a neurological "map" of the areas and proportions of the human brain dedicated to processing motor functions, or sensory functions, for different parts of the body. Nerve fibres—conducting somatosensory information from all over the body—terminate in various areas of the parietal lobe in the cerebral cortex, forming a representational map of the body. NettetMore specifically the ventral posteromedial (VPM) nucleus of the thalamus and the postcentral gyrus (sensory strip) for facial sensation; precentral gyrus (motor strip) for motor supply to the muscles of the jaw. The trigeminal nerve also carries the afferent limb of the corneal reflex in response to stimulation of the cornea.
