f. Cerebellum. The cerebellum has been greatly developed with many
functional subdivisions. All together, it is one of the most important integrators of motor
activity of the body.
g. Cerebrum. In humans, the highest level of nervous control is localized in the
cerebrum. It is at this level that conscious sensation and volitional motor activity are
localized. Even so, we can clearly designate three levels of control within the cerebrum:
(1) Visceral (vegetative) level. This level is concerned primarily with visceral
activities of the body as related to fight-or-flight, fear, and other emotions.
(2) Patterned (stereotyped) motor actions. Here, activities of the body are
standardized and repetitive in nature. An example of a stereo- typed pattern of muscle
activity would be the sequence of muscle actions involved in walking.
(3) Volitional level. The volitional level is the highest and newest level of
control. Here, unique, brand-new solutions can be created.
