PSYC 34500. DRUGS AND BEHAVIOR. This course is an introduction to the pharmacological and psychological mechanisms of drugs that influence brain functioning. We will investigate drug use and drug actions by drawing from scientific investigations of their use. The course will cover basic structure and function of the nervous system, drug classification and development, basic principles of pharmacology, as well as the role of learning and addiction. We will spend most of our time discussing the behavioral, cognitive, and physiological effects of specific drugs of abuse and neuropharmacological use.
