“…Similarly, the latency of the group average AEP decreased of 56 ms. The dominant AEP positive component amplitude decreases from 2 to 5 years to adulthood, showing the developmental changes reported elsewhere (Lippe et al, 2009). VEP and AEP developmental descriptions are detailed in Lippe et al (2007, 2009).…”

“…Auditory evoked potentials triggered by broadband clicks are characterized by a large positive followed by a negative component in the first months of age (Rotteveel et al, 1987; Pasman et al, 1999; Ponton et al, 2000). Depending on the study, the auditory N1 has been reported to appear between 3 and 9 years of age (Tonnquist-Uhlen, 1996; Ceponiene et al, 1998; Pang and Taylor, 2000; Wunderlich and Cone-Wesson, 2006; Sussman and Steinschneider, 2009) and the early P1 appears thereafter (Lippe et al, 2009). …”

Brain development carries with it a large number of structural changes at the local level which impact on the functional interactions of distributed neuronal networks for perceptual processing. Such changes enhance information processing capacity, which can be indexed by estimation of neural signal complexity. Here, we show that during development, EEG signal complexity increases from one month to 5 years of age in response to auditory and visual stimulation. However, the rates of change in complexity were not equivalent for the two responses. Infants’ signal complexity for the visual condition was greater than auditory signal complexity, whereas adults showed the same level of complexity to both types of stimuli. The differential rates of complexity change may reflect a combination of innate and experiential factors on the structure and function of the two sensory systems.

“…Interestingly, in children with sensory hearing loss and those with auditory neuropathy, the P1, N1, and P2 components are present only in those children exhibiting good speech perception skills [9]. However, the children with and without good speech perception skills were not age-matched and this factor could have influenced the results, since CAEPs show substantial changes with maturation [13, 14]. …”

Objective. This study examined the patterns of neural activity in the central auditory system in children with hearing loss. Methods. Cortical potentials and mismatch responses (MMRs) were recorded from ten children aged between 9 and 10 years: five with hearing loss and five with normal hearing in passive oddball paradigms using verbal and nonverbal stimuli. Results. Results indicate a trend toward larger P1 amplitude, a significant reduction in amplitude, and latency of N2 in children with hearing loss compared to control. No significant group differences were observed for the majority of the MMRs conditions. Conclusions. Data suggest that the reduced auditory input affects the pattern of cortical-auditory-evoked potentials in children with a mild to moderately severe hearing loss. Results suggest maturational delays and/or deficits in central auditory processing in children with hearing loss, as indicated by the neurophysiological markers P1 and N2. In contrast, negative MMR data suggest that the amplification provided by the hearing aids could have allowed children with hearing loss to develop adequate discriminative abilities.

“…On the other hand a study, which evaluated LLAEP evoked by noise stimuli observed in children with ages between one month and five years, found mainly the component P2 in all individuals. The latency of this component was of approximately 174 ms in children with an age range between seven and 18 months and of approximately 134 ms in children with an age between 24 and 66 months (17) . Such values, are similar to latency values for the component P1 observed both in the present study, as well as reported by other authors who evaluated children in a similar age range (10,18,22,23) .…”

“…Despite these findings, other studies only infrequently observe the components P1 and N1 in infants and children, with the component P2 being the most encountered (17) . On the other hand, in another study, it was observed that only the P1 peak was clearly present in children of 3 to 7 months of age (18) and that, additionally, the components N1 and P2 are observed with greater frequency from 12 years of age (12) .…”

RESUMO Objetivo O objetivo deste estudo foi monitorar o surgimento e as mudanças nos componentes dos Potenciais Evocados Auditivos de Longa Latência (PEALL) em crianças com audição normal. Método Estudo longitudinal com crianças de ambos os gêneros, sendo: sete crianças com idade entre 10 e 35 meses, e oito crianças com idade entre 37 e 63 meses. A avaliação eletrofisiológica da audição consistiu na análise dos PEALL obtidos em campo sonoro com as caixas posicionadas a 90° azimute, por meio da sílaba /ba/ na intensidade de 70 dBnNA. Cada criança passou por uma avaliação inicial seguida por duas reavaliações após três e nove meses. Resultados Foi observado surgimento dos componentes dos PEALL ao longo dos nove meses de acompanhamento, sendo os componentes P1 e N2 os mais frequentes em crianças desta faixa etária. Não houve diferença estatística no que diz respeito à ocorrência dos componentes P1, N1, P2 e N2 entre as crianças mais novas ou mais velhas. No que tange aos valores de latência, as maiores diferenças ao longo dos nove meses foram observadas no componente P1 para as crianças mais novas e para o componente N2 para as crianças mais velhas. Somente o componente P1 apresentou diferença estatisticamente significante entre os grupos, sendo que foram observados maiores valores de latência entre as crianças mais novas. Conclusão A maturação dos PEALL ocorre gradualmente e o surgimento dos componentes do complexo parece estar mais relacionado à maturação do sistema nervoso auditivo central do que à idade cronológica.
