Mechanism and Theory of Visually Guided Action
The Reinagel lab studies perceptually guided selection of action in the visually behaving rat. Our primary experimental tool is quantitative visual behavior. Much of our effort is focused on building computational models to explain reward-motivated choice behavior in the face of sensory uncertainty. Lesions and pharmacology are used to probe neural mechanisms. One current focus is the speed-accuracy trade-off of rats as they perform different types of visual discriminations. A second focus is blindsight: identifying which visual behaviors are dependent on primary visual cortex in the rat, and characterizing visual decision-making and learning in V1-independent visual behaviors.
