[REGARDING THE SENSORY AND MOTOR HOMUNCULUS] What is the adaptive or evolutionary value to the amount of space dedicated to each body part? How does the human homunculus compare to that of other animals? Why?

Motor homunculus is the form of a topographic representation of
the body part and their correspondent. This is the form of
representation in which the postcentral gyrus of the parietal lobe
is observed. Motor homunculus is the kind of representation of the
primary somatosensory cortex in which correspondence of an area
stimulator. Motor and sensory homunculus are of the relative size
of each body area in which the cerebral cortex is dedicated to that
specific area.
The adaptive and evolutionary value to the amount of the space
which is dedicated to each body of part involves most of the
activity in the cerebrum of the brain cells. The cortex possesses
the functions including the somatosensory cortex and frontal
position of the parietal lobe. Crossing over of the nerve tract the
right portion gets the input while the left portion gets the space
in the brain.
Human homunculus as compared to that of other animals because of
the distorted representation of the human body. There are different
areas of the face that are represented in the different forms and
strange-looking proportions. They possess the sensory from the hand
that terminates the large areas of the brain and result in the
homunculus form. Homunculus man is the kind of popular man who is
sensory part of the cerebral cortex involved different sensation
that takes place in the overall part of the body.
