26 McNeely Intro to Psychology26 Acetylcholine – involved in voluntary movement, learning, memory, and sleep § Too much acetylcholine is associated with depression, and too little in the hippocampus has been associated with dementia. Dopamine – correlated with movement, attention, and learning § Too much dopamine has been associated with schizophrenia, and too little is associated with some forms of depression as well as the muscular rigidity and tremors found in Parkinson’s disease. Norepinephrine – associated with eating, alertness § Too little norepinephrine has been associated with depression, while an excess has been associated with schizophrenia. Epinephrine – involved in energy, and glucose metabolism § Too little epinephrine has been associated with depression. Serotonin – plays a role in mood, sleep, appetite, and impulsive and aggressive behavior § Too little serotonin is associated with depression and some anxiety disorders, especially obsessive-compulsive disorder. Some antidepressant medications increase the availability of serotonin at the receptor sites. GABA (Gamma-Amino Butyric Acid) – inhibits excitation and anxiety § Too little GABA is associated with anxiety and anxiety disorders. Some antianxiety medication increases GABA at the receptor sites. Endorphins – involved in pain relief and feelings of pleasure and contentedness

28 McNeely Intro to Psychology28 ACTING IN THE ENVIRONMENT. MOTOR SYSTEMS AND DISORDERS. Mapping the Motor Cortex Wilder Penfield, a Canadian surgeon, took the next exploratory voyage of the brain's organization starting in the 1950s. While operating on epileptic patients, Penfield applied electric currents to the brain's surface in order to find problem areas. Since the patients were awake during the operations, they could tell Penfield what they were experiencing. Probing some areas would trigger whole memory sequences. For one patient, Penfield triggered a familiar song that sounded so clear, the patient thought it was being played in the operating room. During these operations, Penfield watched for any movement of the patients' bodies. From this information, he was able to map out the motor cortex, the part of the brain you mapped out in this feature's activity.
