P300 is a special evoked potential which tests conscious processing. The idea is to smuggle surprising stimuli between boring stimuli. The EEG is only averaged at the moment a surprising stimulus is displayed. This means it’s far slower to record than the normal evoked potential. On the plus side it’s stronger than the passive one.
The timelapse is played ten times faster.
