Motor and sensory cortical homunculus (preview) - Human Neuroanatomy | Kenhub
Motor and sensory cortical homunculi are distorted representations of body parts, sized in relative proportion to the level of motor, or sensory ability that they are capable of. To watch the full version of this video, click here: https://khub.me/ctlyd

The primary motor cortex (motor area) is the area which corresponds to area 4 of Brodmann and possibly to the part of area 6 which lies in the precentral gyrus. That area of the cortex is responsible for initiation of voluntary movement. However, specific regions within the area are responsible for movements in specific parts of the body. Stimulation of the paracentral lobule produces movement in the lower limbs. The trunk and upper limbs are represented in the upper part of the precentral gyrus, while the face and head are represented in the lower part of the gyrus. This concept is referred to as “Homunculus” and basically, it shows how the brain sees the body. Just like the motor area, the concept of Homunculus can be applied to the sensory area.
On the full version of this video, we will be covering the following:
quick overview of the brain , reminding ourselves of its
main gross, or macroscopic features;
precentral gyrus and postcentral gyrus in more detail;
motor cortical homunculus and the sensory cortical homunculus: we’ll identify the different parts of these homunculi and the pattern that they follow;
clinical [notes] scenario to see how knowing this information could help in that setting.
