Randall Newmark, B.A.

 

 

Randall is a doctoral candidate in the Graduate Program for Neuroscience (GPN). His research focuses primarily on using functional magnetic resonance imaging (fMRI) to characterize the neurobiological underpinnings of episodic and working memory.

 

Specifically, his research identifies areas in the brain that contribute to holding memories ‘on line’ over a short period of time, as well as resolving overlapping memories. He addresses this research using high-resolution imaging techniques to measure the functional contributions of distinct subregions of the medial temporal lobe as well as subfields within the hippocampus. Using manual tracing region-of-interest (ROI) approaches as well as multivariate and univariate analytic techniques, we are able to investigate how the perirhinal, entorhinal, and parahippocampal cortices as well as the subiculum, CA1, and CA3/Dentate gyrus hippocampal subfields function during cognitive processes in working memory.
