Robert Sapolsky: The Biology and Psychology of Depression

Robert Sapolsky delivers a lecture on the biology and psychology of depression, emphasizing that it is a medical disease, not a personal failing. He discusses the increasing incidence of depression, its symptoms like anhedonia and cognitive distortions, and the roles of neurotransmitters, brain circuits, and hormones. Sapolsky stresses the importance of understanding both the biological and psychological components of depression, including the impact of stress and early life experiences. He also touches on various treatments, including medication, ECT, and cognitive behavioral therapy, and highlights the role of genetics and environmental factors in vulnerability to the disease, advocating for reducing the stigma associated with mental illness and seeking help.
