Imagery in rats: Decision making in the face of perceptual ambiguity

Save as calendar entry

Abstract: When we open our eyes, we see a world filled with objects and events. Yet, due to occlusion of some objects by others, we only have partial perceptual access to the events that transpire around us. I will discuss work from my lab suggesting that rats can use imagery to fill in missing details of the world that are expected but hidden from perception. My lab has found that rats make use of an active expectation (i.e., an image) of a hidden visual event. Interestingly, rats only do this under certain conditions, but not others. We explore through behavioral studies the necessary conditions for rats to engage in imagining a hidden event, and its theoretical basis. Additional experiments reveal the role of the dorsal hippocampus in modulating use of an image in an instrumental discrimination. Collectively, the results offer insight into the mechanisms that mediate the flexible use of an image during ambiguous situations.
