MeSH Heading: Event-Related Potentials, P300
Tree Number(s): G07.265.216.500.350; G11.561.200.500.350
Unique ID: D018913
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D018913
Scope Note: 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)
