"Neuromodulation and The Balance Between Goal-Directed and Reactive Behavior"

Abstract: Survival requires the ability to adaptively balance the sustained pursuit of future goals with the need to react quickly to important environmental and internal events. Here, I will discuss my lab’s recent work on the role of neuromodulation in regulating the balance between goal-directed and reactive behavior using optical methods for controlling and monitoring neural activity in mice. I will present evidence that phasic activity in serotonin neurons promotes state-dependent behavioral/emotional reactions, and will discuss new data showing that ramping activity in dopamine neurons signifies the use of an internal model of progress toward a goal.
