Answer:
Atleast 2/3 affected
Explanation:
Post-central gyrus is the primary somatosensory area of the brain. If this area is affected the patient may experience difficulties with proprioception and kinesthesia. Proprioception is the ability to determine the exact location of the body in space. Kinesthesia is the ability to determine the part of the body that moves.
Post-central gyrus may be impaired to a large or small extent during a stroke, this will depend on the area of the body that has been paralyzed as a result of stroke and will also depend on the speed of medical care.
However, it has been confirmed that if a stroke affected all sensations interpreted by the brain only in the face and hands, approximately At least 2/3 of the post-central gyrus would be affected.
