Voluntary motor activity

Which region of the brain receives the conscious sensory information and which triggers the voluntary motor activity?




In brain, conscious sensory information is obtained by the neurons located in the special region which is called postcentral gyrus or sensory gyrus. Gyri are the convolutions of cerebrum. Each of the two postcentral gyri is situated in one of the parietal lobes of cerebrum. The voluntary motor activity is genrally commanded by the neurons located in the precentral gyrus. Each of the two precentral gyri are sitauted in one of the frontal lobes of cerebrum. The names post- and pre-central refers to the fact that the motor and sensory gyri are spaced apart in each of the cerebral hemisphere through the sulcus centralis, a fissure which separates the parietal and frontal lobes.
