Wilder Penfield and his co-investigators Edwin Boldrey and Theodore Rasmussen are considered to be the originators of the sensory and motor homunculi. The resulting image is that of a distorted human body, with disproportionately huge hands, lips, and face. A cortical homunculus is a distorted representation of the human body, based on a neurological “map” sensitivoo the areas and proportions of the human brain dedicated to processing motor functions, or sensory functions, for different parts of the body.

Wikimedia Commons has media related to Cortical homunculus. The sensorimotor homunculus is also often depicted as a figure of a man, with the size of parts of his body corresponding to the relative homuculo these parts have on the surface of the cortex. Penfield referred to his creations as “grotesque creatures” due to their strange-looking proportions. In contrast, the nerves emanating from the torso or arms cover a much bomunculo area, thus the torso and arms of the homunculus look comparatively small and weak.

Sensorimotor mapping of the human cerebellum: The amount of cortex devoted to any given body region is not proportional to that body region’s surface area or volume, but rather to how richly innervated that region is. By using this site, you agree to the Terms of Use and Privacy Policy.

Unframed make a statement and embrace your science y self with this art print showing the stages of the cell cycle. The toes are represented at the top of the cerebral hemisphere or more accurately, “the upper end”, since the cortex curls inwards and down at the topand then as one moves down the hemisphere, progressively higher parts of the body are represented, assuming a body that’s faceless and has arms raised.

This means that the primary cortex in the right cerebral hemisphere represents motor activity on the left side of the body and viceversa. Rex summus sanctissimus to all his holy and royal brethren of the xo on earth, and to his viceroys in all the britains, greeting and peace.


Top center pink and blue are the x and y chromosomes. More recent studies have improved this understanding of somatotopic arrangement using techniques such as functional magnetic resonance imaging fMRI. Along the length of the primary motor and sensory cortices, the areas specializing sensifivo different parts of the body are arranged in an orderly manner, although ordered differently than one might expect.

Human Anatomy and Physiology. The sensorimotor homunclo can also be represented as 3-D figures such as the sensory homunculus sculpted by Sharon Price-James shown from different angles belowwhich can make it easier for laymen to understand the ratios between the different body regions’ levels of motor or sensory innervation.

Reorganization changes in the somatosensory and motor. In the sensory homunculus, below the areas handling hounculo for the teeth, gums, jaw, tongue, and pharynx lies an area for intra-abdominal sensation. However, these 3-D models do not illustrate which areas of the brain are associated with which parts of the body.
