Erika Nyhus

Assistant Professor of Neuroscience and Psychology

(on leave for fall 2017 semester)

I study the neural processes involved in higher-level cognition, including executive functioning and episodic memory. Specifically, my research has examined (1) the neural processes supporting executive functions, (2) the neural processes supporting episodic retrieval, and (3) how neural processes interact for top-down control of episodic retrieval. My research has addressed these topics through behavioral and neuroimaging (electroencephalography (EEG), event-related potential (ERP), and functional magnetic resonance imaging (fMRI)) methods. This research has shown how multiple brain systems process information and interact to perform rich cognitive abilities.

The Nyhus Lab is focused on human executive function and memory.  We approach these topics from a cognitive neuroscience perspective with the goals of understanding the characteristics of mental processes and how they are realized within the brain.  Currently, students in my lab are using brain electrical activity (ERPs) to study the brain processes that underlie attention and memory.  These studies show how attention modulation affects later memory.  In addition, we are interested in how neural oscillations provide a mechanism for interaction among brain regions during memory retrieval.  The lab regularly uses EEG along with behavioral paradigms to examine the moment by moment neural dynamics involved in human learning and memory.

Erika's other interests

Professor Nyhus and family at the beach.When I am not in the lab or in front of my computer analyzing neural oscillations, I spend my time playing with my baby, going to yoga, and enjoying the Maine outdoors. Depending on the season, on the weekends I am at the Farmers' Market, skiing, hiking, or camping with my family. I also love to travel and spent a year living in Spain prior to graduate school and walked the Camino de Santiago.
