The EEG Laboratory
A facility for recording and long-term monitoring of spontaneous (awake, asleep) or evoked electroencephalographic (EEG) activity from the surface or interior of the human and animal brain. The Lab is equipped with three computerized EEG recording systems and has the capability to record from up to 128 electrode sites.
The Brain Dynamics Laboratory
A teaching and research computational facility with multiple computer stations, large (Terabyte) associated data storage units, fast access to supercomputing networks, professional software for data analysis. We develop novel in-house algorithms to investigate the spatio-temporal dynamics of electrical (EEG) and magnetic (MEG) signals from the brain of patients and animals, and computer simulation models, on the way into and out of crises. Epilepsy and progressive brain post-traumatic illnesses are among the dynamical disorders we concentrate upon. Conventional signal processing, image processing and data mining techniques, as well as innovative measures of stability, complexity and information flow in networks of nonlinear systems are utilized for long-term prediction of epileptic seizures. Adaptive feedback control has been implemented for their efficient and effective real-time control via neuromodulation. The research at the Brain Dynamics Lab also assists with the diagnosis, differential diagnosis and evaluation of the treatment of those and other brain dynamical disorders.
Over the years, our research has been supported by federal and state funding agencies (NIH, NSF, DoD, VA, DARPA, the Science Foundation of Arizona), private foundations (American Epilepsy Research Foundation, the Whitaker Foundation) and other organizations (Cyberonics Inc.).
