p300 event related potential – p300 latency
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
La P300 est un potentiel évoqué mesuré en électroencéphalographie P signifie que c’est une onde d’ amplitude positive et 300 qu’elle apparait 300 ms après le début d’une stimulation La P300 aussi appelée P3 n’est pas un potentiel cérébral spécifique, elle représente un ensemble d’activités d’ aires cérébrales variées et largement distribuées,

The present study examined the heritability of the P3 waveform and the N1 P2 and N2 components by assessing the visual event-related potential ERP of 30 monozygotic MZ and 34 dizygotic DZ twin pairs Electroencephalogram activity was recorded from Pz P3 and P4 scalp sites while individuals performed a reaction time task involving two conditions differing in difficulty Genetic modeling indicated substantial genetic influence on P3 amplitude, P3 …

· To establish correlation between the cognitive event-related potential P300 and psychological evaluation with an intelligence test based on the Stanford Binet Intelligence Quotient IQ in patients with DMD and a control group the respective tests were performed in 31 patients with DMD and 30 controls The mean age of the group with DMD was 935 ± 2,88 years, while that in control children was 9,43 ± 2,69 years P = …
· Event-related potentials ERPs are an objectively non-invasive approach for studying information processing and cognitive functions in the brain, The P300 is an important and extensively explored late component of ERPs that has been widely applied to assess cognitive function in epilepsy in previous studies,
The P300 P3 wave is an event-related potential ERP component elicited in the process of decision making, It is considered to be an endogenous potential, as its occurrence links not to the physical attributes of a stimulus, but to a person’s reaction to it,

WHAT IS EVENT-RELATED POTENTIAL? Event-related potentials ERPs are very small voltages generated in the brain structures in response to specific events or stimuli Blackwood and Muir 1990 They are EEG changes that are time locked to sensory motor or cognitive events that provide safe and noninvasive approach to study psychophysiological correlates of mental processes Event-related potentials can be elicited by a …

Because of this general invariance with regard to stimulus type, the P300 component is understood to reflect a higher cognitive response to unexpected and/or cognitively salient stimuli, The P300 response has also been studied in the context of information and memory detection, In addition, there are studies on abnormalities of P300 in depression, Depressed patients tend to have a reduced P200 and P300 amplitude and a prolonged P300 …

· In this paper P300 event-related potential EEG detection was researched and analyzed as follows i According to the experimental paradigm and requirements the original EEG data is organized into training sets and tests sets through a preprocessing that mainly includes data cleaning data subsampling and data normalization to provide data support for the proposal and verification of the algorithm, ii On this …
· There are no event related potential ERP-based studies of attentional bias for substance-related cues among methamphetamine MA dependent patients The study aimed to measure changes in P300 event-related potentials elicited by MA-related words in MA-dependent individuals at baseline and after 3 and 6 months of abstinence examining the relationship of ERP changes to craving
