Dr. Deborah Yurgelun-Todd is a recognized leader in studying brain activity as it relates to behavior. Her laboratory has applied a variety of MR imaging techniques to identify brain changes in mood processing and neurocognitive functions and to examine irregularities in the brains of people who have or are at risk for developing several psychiatric disorders. Using imaging techniques such as structural magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and magnetic resonance spectroscopy (MRS) has led to an improved understanding of both developmental and induced brain changes that lead to altered behavior. This knowledge may eventually result in better and more personalized treatments for patients who have or who are vulnerable to psychiatric disorders.
