Cortical Systems Laboratory

The Cortical Systems Lab, under the direction of Jorge A. Gonzalez-Martinez, MD, PhD, is a neuroscience laboratory studying brain electrophysiology, cognition and language in patients undergoing epilepsy and movement disorder surgery. The main goal of our work is to better understand the neurophysiology of cortical systems in human subjects who undergo stereo-electroencephalograph (SEEG) or deep brain stimulation. Our ultimate goal is to develop new methods for brain mapping and therapeutic options for patients with medically refractory epilepsy, including neuromodulatory/resective procedures and the understanding of the neural mechanisms related to the organization of seizures, language and cognitive functions. The laboratory is highly integrated with the University of Pittsburgh Epilepsy Center and the Carnegie Mellon University Department of Biomedical Engineering.   

Location and Capabilities

The Cortical Systems Laboratory is located in Scaife Hall at the University of Pittsburgh, which is the main medical school building and is attached to UPMC Presbyterian. The lab is located three floors away from the epilepsy monitoring unit, located in UPMC Presbyterian, on the 8th floor. 

Epilepsy Monitoring Unit (EMU)

The laboratory clinical arm is the epilepsy monitoring unit, part of the University of Pittsburgh Epilepsy Center. The epilepsy center at the University of Pittsburgh is one of the leading epilepsy surgery programs in the world, with more than 5,000 adult patient-visit annually. The program offers the opportunity for comprehensive evaluation in a self-contained, eight-bed, adult epilepsy monitoring unit (EMU). The EMU features the latest technology including state-of-the-art, all digital video EEG equipmentin private rooms. Operating around the clock, seven days a week, the unit is staffed by a dedicated team of nurses and EEG technologists specializing in epilepsy and overseen by staff epileptologists. The unit is part of the Comprehensive Epilepsy Center, a multi-disciplinary group of neurosurgeons, neurologists neuroradiologist, neuropsychologist, nurses, residents and fellows who coordinate the care and research related topics for patients with medically refractory epilepsy. Patient Management Conference Meetings (PMCs) are performed weekly, on Mondays, where all aspects of patient care are discussed in an academic and teaching environment. Approximately 50 to 60 invasive monitoring procedures (SEEG) are performed per year in our center.
