Identify the major functions of the hypothalamus, cerebellum, and the reticular formation. Give examples of their functions in terms of real behaviors.
What will be an ideal response?
The hypothalamus is a small forebrain structure that monitors three pleasurable activities-eating, drinking, and sex-as well as emotion, stress, and reward. It also regulates the body's internal state. For example, the hypothalamus works to keep the body at a constant temperature, triggering perspiration when the body is hot and shivering when the body is cold. The cerebellum extends from the rear of the hindbrain, just above the medulla. It consists of two rounded structures thought to play important roles in motor coordination. Damage to the cerebellum impairs the performance of coordinated movements. When this damage occurs, people's movements become awkward and jerky. Extensive damage to the cerebellum makes it impossible even to stand up. The reticular formation is a diffuse collection of neurons involved in stereotyped patterns of behavior such as walking, sleeping, and turning to attend to a sudden noise.
