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.
