NIH-GPP Thesis Presentation: "The Role of Dopamine in Information-Seeking"

PhD Candidate:  Ethan Bromberg-Martin, Department of Neuroscience, Brown University

Date/Time/Location:  May 28 (Thurs), 1:00 PM, Building 49, Room 1A51

Abstract:
The desire for knowledge about the future is a powerful motivator in everyday life, but it is unknown how this desire is created by neurons in the brain. Here I will present a candidate for this role in the spiking activity of midbrain dopamine neurons. I will show that rhesus monkeys actively seek advance information about the size of upcoming rewards, and that the same dopamine neurons that signal the animal’s expectation of “primitive” rewards like food and water also signal the “cognitive” reward of information. This unified neural code for appetitive and informational rewards suggests a new view of reward learning, in which information-seeking has a fundamental role.
