ABSTRACT We have studied EEG asymmetry in normal subjects during verbal and spatial tasks. Recordings were made from the left and right temporal and parietal areas, and the ratios of average power (1–35 Hz) in homologous leads T4/T3 and P4/P3 were computed. This ratio (right over left) was greater in the verbal tasks than in the spatial tasks. With this measure we have been able to distinguish between these two cognitive modes as they occur in normal subjects, using simple scalp recording.
