Influence of diazepam on visual pattern-evoked potentials with due regard to nonstationary effects. Methodological...

The effects of diazepam on visual-evoked potentials (VEP) have been studied. The general effects - increase in latencies and decrease in amplitudes of the main peaks of the VEP - were differentiated by segmented averaging (as a measure for the possible lack of stationariness of the VEP) and by psychological testing (to study the influence of personality traits on medication effects).
