Humans have used mind-altering drugs for thousands of years. These mind altering drugs come in many forms, ranging from common drugs such as caffeine, Adderall, and alcohol, to illicit drugs such as LSD and heroin. Advances in neuroscience and psychology have greatly expanded our capacity to understand how drugs alter neural circuits and how these alterations affect decision making, perception, and memory. This course will explore the connection between drugs, brains, and cognition and incorporate recent discoveries in neuroscience, biochemistry, and psychology. The course will be a combination of lectures and discussion of recent brain and behavior related science news and readings from instructors and students. Class Notes: **Course Requisites: (PSY 101 or PSY 150A1) and PSY 230 and PSY 290A and PSY 297A.
