The primary motor cortex is located in the precentral gyrusand handles signals coming from the ssensitivo area of the frontal lobes. The primary sensory cortex is located in the postcentral gyrusand handles signals coming from the thalamus. However, these 3-D models do not illustrate which areas of the brain are associated with which parts of the body.

Wilder Penfield and his co-investigators Edwin Boldrey and Theodore Rasmussen are considered to be the originators of the sensory and motor homunculi. At the very top end of the primary sensory cortex, beyond the area for the toes, it has traditionally been believed that the sensory neural networks for the genitals occur. This means that the primary cortex in the right cerebral hemisphere represents motor activity on the left side of the body and viceversa.


Retrieved from ” https: A motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

Archived from the original on 8 December The simplification suggests that lesions of the motor cortex will give rise to specific deficits in specific muscles.

The sensorimotor homunculi 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. This is an oversimplification, as it cannot fully show the data set Penfield collected from his brain surgery patients.

Penfield first conceived of his homunculi as a thought experiment, and went so far as to envision an imaginary world in which the homunculi lived, which he referred to as “if”.

More recent studies have improved this understanding of somatotopic arrangement using techniques such as functional magnetic resonance imaging fMRI.

A cortical homunculus 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. The word homunculus is Latin for “little man”, and was a term used in alchemy and folklore long before scientific literature began using it.

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 homknculo expect. The topographical representation of the homunculus is arranged in an anatomical fashion and represents the contralateral side.

However, this is a misconceptionas lesions produce deficits in groups of synergistic muscles.
