Which body parts have the largest representation in the somatosensory homunculus?

For the auditory cortex, the lowest 1,000 Hz in our hearing range covers as much area on the cortex as the upper 8,000 Hz. And finally, the homunculus on the sensory cortex looks barely human. It has a large representation of the face and hands compared with the torso, arms and legs.

What is the somatosensory homunculus quizlet?

A sensory homunculus is a visual illustration of the neurons that will “light-up” when a certain stimulus is received. In other words, if you feel a bug crawling on your finger, the sensory homunculus for your finger will “light-up.” A homunculus is often drawn as a little “person” on the surface of the brain.

What are the differences between the motor homunculus and the somatosensory homunculus?

Motor homunculus is a map showcasing the motor processing of the different anatomical portions of the body while sensory homunculus is a map showcasing the sensory processing of the different anatomical portions of the body.

What is the purpose of the homunculus?

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.

Where is the somatosensory homunculus and what is its purpose?

The sensory homunculus is a map along the cerebral cortex of where each part of the body is processed. The sensations occur all along the body. The impulses from the body will be sent into the spinal cord and eventually back to the brain to be processed. While the trigeminal nerve carries the face’s sensations.

Where is the somatosensory homunculus located?

postcentral gyrus
The postcentral gyrus is the location of the primary somatosensory area that takes the form of a map called the sensory homunculus.

What is the homunculus theory?

In the history of embryology, the homunculus was part of the Enlightenment-era theory of generation called preformationism. The homunculus was the fully formed individual that existed within the germ cell of one of its parents prior to fertilization and would grow in size during gestation until ready to be born.
