“…It peaks at around 200-250 ms in young infants (Wunderlich & Cone-Wesson, 2006). Infants reach the adult latency range of 140-170 ms by the age of 15 months (Barnet, Ohlrich, Weiss, & Shanks, 1975;. Both amplitude increases and decreases with age have been reported (Wunderlich & Cone-Wesson, 2006).…”

“…It has been suggested that one source of the P2 is in extra-lemniscal pathways (Barnet et al, 1975;Ponton et al, 2000). This is supported by its vertex-centered scalp distribution, as well as a maturational trajectory that parallels that of the brainstem potentials (Eggermont, 1988).…”

“…Views on the development of the P2 peak are inconsistent. Some researchers posit that auditory P2 emerges early in infancy (Barnet et al, 1975;Kurtzberg et al, 1984;Novak et al, 1989), while others state that it does not appear until 5-6 years of age (Ponton et al, 2000). This is difficult to resolve since only one positivity, traditionally identified as the P1, is present in infants and young children (Ponton et al, 2000;Kushnerenko et al, 2002;Èeponienë et al, 2002).…”

Objective-Event-related brain potentials (ERP) may provide tools for examining normal and abnormal language development. To clarify functional significance of auditory ERPs, we examined ERP indices of spectral differences in speech and non-speech sounds.Methods-Three Spectral Items (BA, DA, GA) were presented as three Stimulus Types: syllables, non-phonetics, and consonant-vowel transitions. Fourteen 7-10-year-old children and 14 adults were presented with equiprobable Spectral Item sequences blocked by Stimulus Type.Results-Spectral Item effect appeared as P1, P2, N2, and N4 amplitude variations. The P2 was sensitive to all Stimulus Types in both groups. In adults, the P1 was also sensitive to transitions while the N4 was sensitive to syllables. In children, only the 50-ms CVT stimuli elicited N2 and N4 spectral effects. Non-phonetic stimuli elicited larger N1-P2 amplitudes while speech stimuli elicited larger N2-N4 amplitudes.Conclusions-Auditory feature processing is reflected by P1-P2 and N2-N4 peaks and matures earlier than supra-sensory integrative mechanisms, reflected by N1-P2 peaks. Auditory P2 appears to pertain to both processing types.Significance-These results delineate an orderly processing organization whereby direct feature mapping occurs earlier in processing and, in part, serves sound detection whereas relational mapping occurs later in processing and serves sound identification.

“…Although P 50 is the least studied of the auditory ERPs, some early reports detailed P 50 latency and amplitude values stating that they were not affected by factors such as age (Barnet et al, 1975) or attention (Picton and Hillyard, 1974). More recently, reports described extensive changes in P 50 with maturation, beginning with its domination of the P 50 -N 100 -P 160 complex in young children (Sharma et al, 1997;Ceponiene et al, 2002) to its small amplitude in adults.…”

Objective: The auditory Event-Related Potentials (ERP) of component P 50 to sound onset and offset have been reported to be similar, but their magnetic homologue has been reported absent to sound offset. We compared the spatio-temporal distribution of cortical activity during P 50 to sound onset and offset, without confounds of spectral change. Methods: ERPs were recorded in response to onsets and offsets of silent intervals of 0.5 s (gaps) appearing randomly in otherwise continuous white noise and compared to ERPs to randomly distributed click pairs with half second separation presented in silence. Subjects were awake and distracted from the stimuli by reading a complicated text. Measures of P 50 included peak latency and amplitude, as well as source current density estimates to the clicks and sound onsets and offsets. Results: P 50 occurred in response to noise onsets and to clicks, while to noise offset it was absent. Latency of P 50 was similar to noise onset (56 ms) and to clicks (53 ms). Sources of P 50 to noise onsets and clicks included bilateral superior parietal areas. In contrast, noise offsets activated left inferior temporal and occipital areas at the time of P 50 . Source current density was significantly higher to noise onset than offset in the vicinity of the temporo-parietal junction. Conclusions: P 50 to sound offset is absent compared to the distinct P 50 to sound onset and to clicks, at different intracranial sources. P 50 to stimulus onset and to clicks appears to reflect preattentive arousal by a new sound in the scene. Sound offset does not involve a new sound and hence the absent P 50 . Significance: Stimulus onset activates distinct early cortical processes that are absent to offset.
