Dr. Pouratian's primary
neurosurgical interest is in surgeries that preserve and restore functional to
patients, including movement disorder surgeries, surgeries for psychiatric
conditions, and surgeries for peripheral nerve injuries and tumors. In order to
do these surgeries, Dr. Pouratian uses advanced neuroimaging and brain and
nerve mapping techniques, including functional MRI, cortical stimulation
mapping, electrocorticographic (ECoG) mapping, optical imaging of intrinsic
signals, and intraoperative EMG and nerve conduction studies.
Dr. Pouratian's research focuses
on further developing these mapping tools in order to expand the surgical
indications and to develop new therapies for functional preservation and
restoration. He is particulary interested in studying brain mapping signals to
develop brain-computer interfaces to help patients with severe motor and
