Division for Neuropsychiatry and Neuromodulation

Program for Neuropsychiatry and Neuromodulation

at Massachusetts General Hospital

Our research uses combinations of neuroimaging and brain stimulation to investigate how the brain connects and interacts within itself and how interventions can create positive change to these connections.​

Critical translational efforts are geared towards applying the paradigms and methods of neuroscience to develop high-impact clinical tools, identify biomarkers, discover treatment targets, and design.

The scope of our work includes basic, translational and clinical projects focused on circuit neuroscience. Questions include the anatomy and physiology of disease-relevant networks, the investigation of pathophysiological mechanisms at the circuit level (with an emphasis on transdiagnostic processes and the role of plasticity) and the translational development of practical tools to support clinical decision-making (e.g. biomarkers and predictors of response). In addition, we have a strong focus on the discovery of treatment targets that support the development of individualized precision therapeutics, with an emphasis on device-based brain stimulation interventions.

Treatments Offered by the PNN

Transcranial Magnetic Stimulation

The Transcranial Magnetic Stimulation (TMS) Clinical Service provides non-invasive treatment for patients with major depressive disorder who are unable to find relief through antidepressant medications or psychotherapy.


In 2016, under Dr. Cassano’s leadership, the MGH Psychiatry Photobiomodulation Clinic was started at the MGH CATSD and DCRP programs, for the off-label use of transcranial photobiomodulation in psychiatry.

Transcranial Direct Current Stimulation

We are evaluating transcranial direct current stimulation (TDCS) to treat executive dysfunction in patients with traumatic brain injury, frontotemporal dementia, ADHD, schizophrenia, depression and bipolar disorder.

Experimental Protocols

At the cutting edge of psychiatry, we are investigating new and exciting methods of treating mental illnesses and disorders. Find out more on our research page.
