How Dopamine Impacts Brain Function | Dr. Mark D'Esposito & Dr. Andrew Huberman

In this podcast episode, Dr. Andrew Huberman interviews Dr. Mark D'Esposito about working memory and the role of dopamine. Dr. D'Esposito explains working memory as the ability to hold and manipulate information in mind, emphasizing its importance as a foundation for cognition. He details the brain circuitry involved, particularly the frontal cortex, and how dopamine modulates persistent neural activity to maintain information. The discussion covers how dopamine impacts working memory, noting that optimal levels are crucial, and that both genetic factors and behavioral measures like memory span tasks can serve as proxies for assessing dopamine levels.
