Margaret Bradley, PhD

Dr. Bradley received her doctorate in Experimental (Cognitive) Psychology from the University of Wisconsin-Madison. She is currently a research professor and the associate director for NIMH Center for the Study of Emotion and Attention. Research interests focus on studying the neural and physiological mechanisms involved in affective and attentional processing in people with and without diagnosable anxiety disorders. Drawing on an animal model of motivation, our lab is mapping the subcortical and cortical neural circuits involved in emotional perception and imagery. In addition to investigating neural processes using fMRI and dense-sensor EEG, we measure autonomic and somatic indices of affective and attentional mobilization, including cardiovascular, electrodermal, electromyographic, eye movement, and other physiological measures. How emotion and attention affect later memory performance, measured in both the brain and body, is another active research area.
