The homunculus is a spatial representation of the cortical topography of the
somato-motor strip which is dedicated to either motor or sensory function.
The two have different structural details, since there are sensory inputs
from non-motor areas.
Some people have tried to create 3D creatures which show the spatial
distortions, with the enlarged surface proportionate to the motor expression or sensory sensitivity, with varied results.
See if you can identify the differences between the sensory and motor
version, and also critique the accuracy of the artist’s rendition of these
Have fun with the exercise!
