What is Memory Neuroscience at Vassar College?

Our memory is one of our most precious abilities. Memory guides adaptive decision-making, triggers complex emotion, and shapes our conscious experience. A principle endeavor in the field of neuroscience is understanding the nature of memory; how it is constructed, stored, modified, and retrieved in the brain. In the Memory Neuroscience lab at Vassar College, we study how memory is organized and retrieved in the brain at the level of molecules, structure, and function. A major emphasis in our lab is the study of aversive (fear) memory and the neurobiological underpinnings of fear memory generalization. Generalization describes the transfer of conditioned responding to stimuli that perceptually resemble, but do not exactly match, the original conditioned stimulus. Generalization is ubiquitous across species, however the neuronal mechanisms remain poorly understood. The study of generalization has high translational relevance considering that both anxiety-related disorders and post-traumatic stress disorder (PTSD) are thought to be, at least in part, related to the overgeneralization of memory. To test questions related to fear memory generalization, we apply neuroscience tools for visualizing and manipulating memory processes in the brain.

The goal of our resarch program is to advance understanding of memory, with the ultimate goal of translating our work into treatments for disorders of learning and memory, such as post-traumatic stress disorder (PTSD) and anxiety-related disorders.

Our research is currently funded by the National Institue of Mental Health R15 MH127534-01.
