Event-Related Potentials, P300 - Physiology
Research News and Information
Definition of 'Event-Related Potentials, P300'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) Common names: Event-Related Potentials, P300; Event Related Potentials, P300; Event-Related Potential, P300; P300 Event-Related Potential; P300 Component; P300 Components; Event-Related Potentials, P3; Event Related Potentials, P3; Event-Related Potential, P3; P3 Event-Related Potential |

OBJECTIVES: The aims of this study were: to investigate the postexcitatory inhibition of cortical evoked potentials on auditory paired-click stimulation in patients with Parkinson's disease (PD), to analyze the correlation of N1-P2 amplitude ratios ... Read more...
9 Sep 2009 It has been proposed that psychophysiological abnormalities in schizophrenia, such as decreased amplitude of the evoked potential component P300, may be genetically influenced. Studies of heritability of the P300 have used different and typically ... Read more...
ERPs in anterior and posterior regions associated with duration and size discriminations.
30 Aug 2009 The main objective of the present study was to determine whether event-related potentials (ERPs) predominant in prefrontal cortex (PFC) respond in a similar fashion to ERPs predominant in posterior parietal cortex (PPC) in duration and size ... Read more...
