  • Interaction of Episodic Memory and Decision-Making Using fMRI and behavioral methods

Research Abstract:

My laboratory studies the cognitive process and neural mechanisms underlying how people both deliberately and automatically recover memories. Our research particularly focuses on how regions within the prefrontal cortex contribute to the deliberate retrieval of memories and how regions in other parts of the brain may instead regulate more automatic expressions of memory. Tools used in the laboratory include behavioral experiments, decision modeling, and brain imaging with functional magnetic resonance imaging (fMRI). Our newest research suggests there may be separate implicit and explicit decision mechanisms that regulate the expression of memory content and that each demonstrates different operating characteristics and neural substrates.
