Abstract : Interhemispheric differences in visual evoked potential amplitude (microvolts root mean square) were measured in five right-handed male subjects. Five different stimuli were used, and each subject participated in 3 similar test sessions. The stimuli included one gray, two vertical grids, and two random-dot textures. The results showed that interhemispheric asymmetries in amplitude are generally consistent for a given subject, and most subjects show greater amplitude in the right side of the brain. There was no differences among four of the stimuli in the degree of asymmetry elicited: one stimulus showed no asymmetry. Some of these stimuli will be used in a future study to determine if there is a relationship between the degree of hemispheric asymmetry and various performance measures in sonar operators.
