Trey Hedden, Ph.D.
Trey Hedden, Ph.D., uses multiple neuroimaging techniques to study how advanced aging and age-related disorders affect brain networks involved in attention and memory. He received his B.A. in cognitive science from the University of Virginia, his Ph.D. in cognitive psychology from the University of Michigan, and did postdoctoral research at Stanford University and MIT. He is currently an assistant in neuroscience at the Athinoula A. Martinos Center for Biomedical Imaging, Department of Radiology, Massachusetts General Hospital.
The Default NetworkYour Mind, on Its Own Time
Over the last 20 years, researchers have been interested in what the brain does during periods of supposed inactivity. They discovered that when someone appears to be doing nothing at all, a network of brain regions—named the default network—is hard at work, allowing for the rich inner lives inside our heads. Applying what is known about the default network to diseases like Alzheimer’s allows for new possibilities for diagnosis and evaluation of treatments.
