The cerebral hemispheres are responsible for functions such as control of muscles. The right hemisphere mainly controls the motor and sensory functions on the left side of the body. Damage to the right side would result in impaired function on the left side of the body. The motor cortex controls voluntary motor activity. Broca's area controls motor speech. Cognitive functions are attributed to the association cortex. The right side of the body's motor activity is controlled by the left cerebral cortex.
