How the brain’s internal states affect decision-making

Matthew Smith and Byron Yu, along with former Ph.D. student Ben Cowley (Ph.D., SCS ’18), have studied the neural basis through which internal states in the brain affect decision-making over an extended period of time. Through recording the activity of populations of neurons simultaneously in two brain areas, they were able to gain unprecedented insight into how the waxing and waning of our mental state influences the decisions we make.
