[Visually evoked P300 waves].
The event-related potentials after a competitive visual stimulation are presented. The stimulation with target stimuli results in two pronounced positive potentials in the grand-average, the P2 and the P3 component of the ERP, and a long-lasting positivity following the P3 wave. Similar but smaller potential components are elicited by non-target stimuli. Some examples of individual ERP demonstrate the high degree of inter-individual variability, as in the positive components as in the restoration of the poststimulus baseline. Some aspects of a possibly fundamental difference between visually and acoustically elicited P300 waves are demonstrated.
