We want to understand how the brain does decision-making. This requires an understanding of both the behavioral and neural mechanisms involved. We take an integrative approach using mice, in which we can combine both simple and sophisticated quantitative behavioral measurements, with powerful molecular and genetic tools and monitoring techniques to delineate molecular mechanisms within specific cell-types in identified circuits that control decision-making processes.
