The Hetrick Lab is dedicated to the discovery of neurocognitive mechanisms associated with the etiology of schizophrenia and bipolar disorder and the development of innovative interventions for these syndromes. The lab is especially interested in clinical translational science approaches that leverage basic science methods and nonhuman models to understand and ameliorate complex human issues. The lab utilizes behavioral, cognitive, and brain imaging techniques, including electromyography (EMG), electroencephalography (EEG), and functional and structural magnetic resonance brain imaging (MRI). We have laboratory facilities in the Department of Psychological and Brain Sciences and at Larue D. Carter Memorial Hospital, which is a teaching and research site for the IU Department of Psychiatry. We have ongoing collaborations with the Indiana University laboratories of Drs. Brian F. O'Donnell, Aina Puce, Sharlene Newman, Olaf Sporns, Michael Jones, and Alan Breier.
