Child and adolescent event-related potential component morphology, amplitude and latency to standard and target stimuli in an auditory oddball task

Emotional Significance of the Stimulus and Features of the Personality as Factors Reflected in the Pattern of Evoked EEG Potentials

“…It is known that the highest amplitude of the Р3 is observed in those subjects who perform an experimental task best and are characterized by greater cognitive maturity [70]. As was shown [119], the duration of the interstimulus interval influences the amplitude of the Р3 independently of the probability of presentation of the stimulus; the shorter the interval, the higher the Р3 amplitude.…”

“…It was also mentioned that the amplitude of the Р2 wave noticeably depends on the activity of the nonspecific cerebral systems (in particular, on the functional state of the RF). This amplitude increases with age (within a certain range); this phenomenon can reflect the level of maturity of the reticulo-cortical connections [33,70]. There are data on correlation of the characteristics of component Р2 with the phase synchronization of the field electrical activity of the brain within the theta frequency range.…”

“…It was demonstrated that the amplitude of component Р3 depends on the level of attention [118], on the probability of presentation of the target stimuli within a train of the standard ones (the less frequently the target stimuli is presented, the higher the Р3 amplitude), and also on the subjective value and motivational significance of the stimuli [70]. It is known that the highest amplitude of the Р3 is observed in those subjects who perform an experimental task best and are characterized by greater cognitive maturity [70].…”

Maturation of CAEP in infants and children: A review

“…Over time, the early components, P 1 and N 1 , which are often absent in the very young, become more frequently evoked and greater in amplitude than their later counterparts, P 2 and N 2 . The gradual change in morphology to the classic adult form is due in great part to this as well as to a decrease in N 2 amplitude (Johnstone et al, 1996) and a generalised decline in peak latencies. The general waveform morphology reaches maturity around 12 years of age although the latencies and amplitudes of the various components continue to change beyond this age (Ponton et al, 2000).…”
