Brain Computer Interface

As a neurosurgeon specializing in epilepsy surgery, I am privileged to have direct contact with the brain. For example, during the workup for patients undergoing evaluation for epilepsy surgery, we obtained brain signals by performing electroencephalogram (EEG) or intracranial recordings including electrocorticography (ECOG) to identify the origin of the seizures, which are abnormal neuronal activities. The recordings obtained from these studies give us a tremendous amount of information on how the brain works. How does the brain control our motor movements? How does the brain generate and understand speech? Furthermore, these brain signals can be used to design and control robotic devices to perform important functions for a patient who has lost these functions from stroke or spinal cord injuries. Our goal is to use brain computer interface devices to help design periprosthetic devices to improve the lives of these patients.
