Working Memory and Cognitive and Neural Bases of Nondeclarative Memory

Research Strength: Behavior: Cognition and Emotion

My interest in human memory focuses on the cognitive and neural bases of working memory and nondeclarative memory. Topics motivating recent and current research include: the organization of working memory function in prefrontal cortex; the differential contributions of prefrontal cortex and basal ganglia to visual working memory; nonmnemonic control processes that contribute to working memory performance; the mechanisms underlying repetition priming phenomena; and a novel mechanism that may support spatial working memory performance. Experimental methods employed in my laboratory include functional magnetic resonance imaging (fMRI), behavioral testing of neurological patients and of healthy young adults, and repetitive transcranial magnetic stimulation (rTMS).
