Ann Graybiel studies the basal ganglia, forebrain structures that are profoundly important for normal brain function. Dysfunction in these regions is implicated in neurologic and neuropsychiatric disorders ranging from Parkinson’s disease and Huntington’s disease to obsessive-compulsive disorder, anxiety and depression, and addiction. Graybiel’s laboratory is uncovering circuits underlying both the neural deficits related to these disorders, as well as the role that the basal ganglia play in guiding normal learning, motivation, and behavior.
Graybiel’s team uses electrical recordings, fiber photometry and 2-photon microscopy, dopamine release measurements and behavioral tests, and genetic engineering in mice to study the functions of the basal ganglia, a large region in the forebrain that has been linked to disorders ranging from Parkinson’s disease to OCD, autism spectrum disorders, depression, stress-related disorders, and addictive behaviors. Projects in the lab focus on discovering neural mechanisms underlying motivationally based decision-making, and habit-learning. The lab examines how these networks connect to the action systems of the brain to build up our behaviors and habits, as well as how they work in decision-making under conditions of motivational conflict such as cost-benefit conflict.
The processes examined by the Graybiel laboratory are linked to neurochemicals such as dopamine and serotonin, and they are also interested in therapeutics, for example through development of chronic drug delivery systems.
Ann Graybiel ’71 joined the MIT faculty in 1973, where she is a member of the Department of Brain and Cognitive Sciences and an Institute Professor, the highest academic award at MIT. In 2001, she was appointed Investigator at the McGovern Institute.
