Archived from the original on The word homunculus is Latin for “little man”, and was a term used in alchemy and folklore long before scientific literature began using it. 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.

In contrast, the nerves emanating from the torso or arms cover a much smaller area, thus the torso and arms of the homunculus look comparatively small and weak. 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.
Going further down the cortex, the different areas of the face are represented, in approximately top-to-bottom order, rather than bottom-to-top as before.
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 areas these parts have on the surface of the cortex. Wikimedia Commons has media related to Cortical homunculus.
Semsitivo New Clitoral Homunculus? A cortical homunculus, or “cortex man”, illustrates the concept of heuristically representing the body lying within the brain. However, more recent research has suggested that there may be two different cortical areas for the genitals, possibly differentiated by one dealing with erogenous stimulation and the other dealing with non-erogenous stimulation.

Penfield first conceived of his homunculi aensitivo a thought experiment, and went so far as to envision an imaginary world in which the homunculi lived, which he referred to as “if”. In addition, their drawings and later drawings derived from theirs became perhaps the most famous conceptual maps in modern neuroscience because they compellingly illustrated the data at a single glance.
We publish a new selection of homunculus pictures which may also be downloaded as wallpapers. Rather than the sharp delineation between different body areas shown in the drawings, there is actually significant overlap between neighboring regions.
