Dr Nader Pouratian is a neurosurgeon-scientist whose clinical practice focuses on using brain stimulation to alleviate neurologic and psychiatric disease. His research aims to understand the network basis of disease and therapeutic brain stimulation using multiple brain mapping techniques, including both non-invasive and invasive approaches. Using functional magnetic resonance imaging and MR tractography, his lab aims to understand the how brain connections are affected in the diseases treated with brain stimulation. Dr Pouratian also uses the operating room as a laboratory, using this unique opportunity to study the physiology of the human brain in patients undergoing awake brain surgeries. Techniques used in the operating room including measuring local field potentials, electrocorticography, and neuronal spiking activity. By using a multimodality technique, he aims to understand brain networks from the cellular through the systems level.

At this time, his laboratory primarily focuses on investigating Parkinson's disease, chronic pain, depression, and consciousness. He is funded by the National Institute of Biomedical Imaging and Bioinformatics. He is an associate professor of neurosurgery and radiation oncology, affiliate faculty in bioengineering, and a member of the UCLA Neuroscience program and Brain Research Institute.
