Event-Related Potentials, P300

A late-appearing component of the event-related potential. P stands for positive voltage potential and 300 represents 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)
