BIOL 251: Cerebral Hemispheres

Cerebral cortex: 

Grey matter that is divided into four functional areas or lobes (frontal, temporal, parietal, occipital, and insula).

It interprets and integrates sensory input, controls voluntary skeletal muscles for locomotion, functions in decision making, intelligence, personality, and emotional processing

Primary somatosensory cortex: 

Located in the postcentral gyrus and along with association area, it maps sensations from the periphery.

Primary motor cortex:

Located in the precentral gyrus, it controls conscious movement of skeletal muscles.

Basal nuclei:

Subcortical motor centers that assist in initiation and stopping of skeletal muscle movements.
