  2. Cortical homunculus - Wikipedia

    en.wikipedia.org/wiki/Cortical_homunculus

    A 2-D model of cortical sensory homunculus. A cortical homunculus (from Latin homunculus 'little man, miniature human' [1] [2]) 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.

  3. Homunculus - Wikipedia

    en.wikipedia.org/wiki/Homunculus

    The homunculus is commonly used today in scientific disciplines such as psychology as a teaching or memory tool to describe the distorted scale model of a human drawn or sculpted to reflect the relative space human body parts occupy on the somatosensory cortex (the sensory homunculus) and the motor cortex (the motor homunculus). Both the motor ...

    The motor cortex is the region of the ... Penfield drew a picture of a human-like figure stretched over the cortical surface and used the term "homunculus ...

  5. Primary motor cortex - Wikipedia

    en.wikipedia.org/wiki/Primary_motor_cortex

    There is a broad representation of the different body parts in the primary motor cortex in an arrangement called a motor homunculus (Latin: little person). [7] The leg area is located close to the midline, in interior sections of the motor area folding into the medial longitudinal fissure. The lateral, convex side of the primary motor cortex is ...

  6. Brodmann area 4 - Wikipedia

    en.wikipedia.org/wiki/Brodmann_area_4

    That is, the legs and trunk fold over the midline; the arms and hands are along the middle of the area shown here; and the face is near the bottom of the figure. Because Brodmann area 4 is in the same general location as primary motor cortex, the homunculus here is called the motor homunculus.

  7. Topographic map (neuroanatomy) - Wikipedia

    en.wikipedia.org/wiki/Topographic_map_(neuroanatomy)

    Unlike the topographic maps of the senses, the neurons of the motor cortex are efferent neurons that exit the brain instead of bringing information to the brain through afferent connections. The motor system is responsible for initiating voluntary or planned movements ( reflexes are mediated at the spinal cord level, so movements associated ...

  8. Cortical stimulation mapping - Wikipedia

    en.wikipedia.org/wiki/Cortical_stimulation_mapping

    Cortical stimulation mapping led to the development of a homunculus for the motor and sensory cortices, which is a diagram showing the brain's connections to different areas of the body. An example is the cortical homunculus of the primary motor cortex and the somatosensory cortex, which are separated by the central sulcus.

    Homunculus Nebula, a part of the Eta Carinae Nebula; Cortical homunculus, also known as the Penfield homunculus, a physical representation of the primary motor cortex of the rest of the body; Fetiform teratoma, a rare cyst having a fetal structure; The homunculus argument is a fallacy arising most commonly in the theory of vision
