N2 - A need exists to develop a better predictive tool for estimating deterioration in the visual system. This pilot study examined changes in EEG spectral power of subjects with varying visual impairments. EEG activity of five subjects was recorded while playing a driving game both with and without their corrective glasses. The spectral power at three channel locations in the occipital lobe were obtained and compared. Subjects having better vision displayed higher spectral power in both the theta and alpha band regions. An increase in average spectral power for the alpha band region, with changes in spectral power topographies in the theta band region, was observed. The results suggest that spectral power in the alpha and theta bands may depend on activation in the visual system. This focus, to better understand the interactions between the human brain and the visual system, will aid in developing improved visual prosthetic devices.
