A wireless, portable EEG device was developed and validated in the clinic, leading to FDA approval and commercialization. Functional near-infrared spectroscopy (fNIRS) is similar to EEG in cost and portability, and provides a complementary set of information about the functional status of the brain. We will describe the concurrent use of these modalities, EEG+fNIRS, in healthy adult volunteers. Results show that spontaneous changes in neural activity drive hemodynamics. Results also indicate that functional neuroimaging data during task performance is more accurate than that of data from individual modalities alone. EEG+fNIRS may provide a suitable platform for the diagnosis and screening of acute and chronic brain disorders.
Dr. Omurtag is Associate Professor in Biomedical Engineering at the University of Houston. He holds a Ph.D. in Mechanical Engineering from Columbia University. His post-doctoral training was at the Mount Sinai School of Medicine in computational neuroscience. His research focus is on the diagnostic utility of portable functional neuroimaging devices. He works on applications of simultaneous EEG and functional near-infrared spectroscopy (fNIRS).
