We studied the time and amplitude parameters of visual evoked potential components during performance of a visuospatial task under conditions of involuntary and voluntary attention. The right hemisphere dominated to a great extent with respect to the latencies of the components studied. Transient stagewise dominance of each hemisphere with respect to the level of cortical activity was also observed.
