This workshop will provide a basic understanding of the anatomy, physiology, and psychology of steady-state visual evoked potential (SSVEP) measurements, and their applications in biofeedback. It will begin with a review of the basic science of the averaged visual evoked potential (AVEP), how it is produced, and its major components. There will be a brief discussion of how the various components of the AVEP relate to psychological variables in general, and attention in particular.
The relationship between the AVEP and the SSVEP will be described, which will provide a basis for understanding how the SSVEP may be used for diagnostics, and in biofeedback applications. There will be a review of experimental results which give insight into the relationship between SSVEP measurements and clinical conditions such as ADD/ADHD and autism. There will also be a demonstration of SSVEP measurement using filters synchronized to the visual stimulation. This workshop should allow the participant to better understand this emerging modality, and to pursue possible applications in the diagnostic and clinical setting.
Dr. Collura has over 30 years experience as a biomedical engineer and neurophysiologist. He has conducted clinical research and development and system design, in the areas of evoked potentials, microelectronics, human factors, EEG mapping for epilepsy surgery, and neurofeedback. His graduate work focused on the real-time measurement of visual and auditory evoked potentials, and relationships with selective attention in a vigilance task. He then spent 8 years with AT&T Bell Laboratories as a technical staff member and supervisor in the areas of integrated circuit technology, computer graphics, networking, and man/machine interfaces. He then served from 1988 to 1996 on the Staff of the Department of Neurology, Cleveland Clinic Foundation, where he conducted research and development in EEG mapping for epilepsy surgery, long-term EEG monitoring, and DC brain potentials. As a consultant to industry, he has designed software and hardware for computerized tomography, automated radiometry, and automated imaging. Since 1995, he has been founder and president of BrainMaster Technologies, Inc. He has published over 100 peer-reviewed journal articles, book chapters, abstracts, and papers. He has 2 patents and 3 patents pending, all in the areas of neurofeedback, electrode technology, and evoked potential methods and systems. His current interests focus on research and development of automated neurofeedback systems, evoked potential neurofeedback, and low-cost quantitative EEG. He is a licensed Professional Engineer in Ohio and Illinois, is a past board member of the International Society for Neuronal Regulation (ISNR), and is president-elect of the Neurofeedback Division of the Association for Applied Psychophysiology and Biofeedback (AAPB).
