But one of 2013 recipients of the NIH Director’s New Innovator Award, Kay Tye of the Massachusetts Institute of Technology (MIT), Cambridge, MA, is up for the challenge. In a high-risk, high-reward research project, she’s trying to find ways to control food cravings by reprogramming the brain, where the behavior begins.
Tye says her interest in the human brain began when she was a freshman at MIT and met H.M.—perhaps the most iconic patient in the history of brain research. H.M. was intriguing because experimental brain surgery had left him unable to form new memories, yet the old ones remained intact—a sign that there are multiple memory systems at work in the human brain. From that point on, she knew she wanted to study neuroscience, specifically memory. She began with emotional memories, including those associated with food, images, and songs.
