Ett sent inträdande inslag i den händelserelaterade reaktionspotentialen. P står för positiv laddning och 300 anger 300 millisekunder "poststimulus". Reaktionens amplitud ökar med oförutsedda, osannolika eller högt signifikanta stimuli, och utgör därmed ett index över mentala aktivitet.
A late-appearing component of the event-related potential. P300 stands for a positive deflection in the event-related voltage potential at 300 millisecond poststimulus. Its amplitude increases with unpredictable, unlikely, or highly significant stimuli and thereby constitutes an index of mental activity. (From Campbell, Psychiatric Dictionary, 6th ed)
