09/25 | Scott | Timothy A. Krausz, Alison E. Comrie,Ari E. Kahn, Loren M. Frank,Nathaniel D. Daw, Joshua D. Berke | Dual credit assignment processes underlie dopamine signals in a complex spatial environment Authors investigate how expectations of future reward are updated through experience. In rats traversing a complex maze, they show that nucleus accumbens dopamine scales with reward expectation from each location. This expectation signal propagates between adjacent spatial locations and is also inferred using knowledge of maze structure. |
