Parkinson"s disease. : serotonin > mood control, hunger, sleep, and arousal, neurotransmitters bind to the receptors of the receiving neuron in a key-lock mechanism, agnostics - mimic neurotransmitter, excites, antagonists -stop nts from fitting into their lock . Sympathetic nervous system: division of the ans that arouses or excites the body in stressful situations. Parts of the brain: brainstem - the oldest part of the brain, beginning where the spinal cord swells and enters the skull. Sensory information from the sense organs goes to the hippocampus. If important enough, they are processed in the hippocampus and established as lasting memories: hypothalamus lies below (hypo) the thalamus; directs several maintenance activities like eating, drinking, body temperature, sexual behavior. Cerebral cortex and the lobes: cerebral cortex - the intricate fabric of interconnected neural cells that covers the cerebral hemispheres, frontal lobes (forehead) Carries out many important functions such as the ability to judge, plan, impulse control, and process new memories.
