About
Dr. Grella is an Assistant Professor, Department of Psychology, Loyola University Chicago. Her research is focused on the mechanisms by which memories change across time and how they are updated to incorporate new information. Memories are stored in the brain as cellular ensembles activated during learning and then reactivated during retrieval. However, these ensembles are inherently malleable. She is specifically interested in this malleability. Memory malleability, and the ability to incorporate new information and update environmental representations accordingly is a critical component of behavioral flexibility in learning and memory. She is investigating the involvement of noradrenergic and dopaminergic projections to the hippocampus in assigning new networks to mediate encoding that reflects environmental change.
