    Cortical homunculus - Wikipedia

    • 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 portions of the human brain dedicated to processing motor functions, and/ or sensory functions, for different parts of the body. Nerve fibres—conducting somatosensory information fr… See more

    Types

    A motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body. The primary motor cortex is located in the precentral gyrus, and handles signals coming fro… See more

    Arrangement

    Along the length of the primary motor and sensory cortices, the areas specializing in different parts of the body are arranged in an orderly manner, although ordered differently than one might expect. The toes are represe… See more

    Discovery

    Wilder Penfield and his co-investigators Edwin Boldrey and Theodore Rasmussen are considered to be the originators of the sensory and motor homunculi. They were not the first scientists to attempt to objectify human brai… See more

    How does the brain map homunculus?
    mpared with the brain maps each sensory receptoronto the cortex rather than considering the area of the body where the sensor is located. The more receptors there are in a given area of skin, the larger that area’s map will be rep sented on the surface of the cortex. As a result, the size of each body region in the homunculus is relate
