(damage to this will cause a coma) - Thalamus: Greek for “inner chamber” is the brain’s sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex(coordination and sensory integration) - Cerebellum: “little brain” attached to the rear of the brainstem; helps coordinate voluntary movements and balance (walking, playing games, playing instruments); plays a role in emotions, hearing, and touch. - Limbic system: pleasure, memory problems; a ring of structures at the border of the brainstem and cerebral cortex; it helps regulate important functions such as memory, fear, aggression, hunger, and thirst, and includes the hypothalamus, hippocampus, and amygdale o Hypothalamus: (most important) a neutral structure lying below the thalamus; it helps regulate
