motor control the generation and coordination of movement patterns to produce function; it may either control movements of the body in space or stabilize the body in space. See also postural control.
postural control motor control that stabilizes the body in space by integrating sensory input about body position (somatosensory, visual, and vestibular input) with motor output to coordinate the action of muscles and keep the body's center of mass within its base of support. An important aspect of postural control is the righting reactions. Called also balance.
stimulus control any influence exerted by the environment on behavior.
