“…Although no explicit analysis was carried out by the authors, a comparison of the ERPs elicited by regularity-conforming tones in positions 3 and 5 of the sequence shows clear signs of RP (see Fig. 2 in Schadow et al, 2009). RP has been reported with even more complex regularities as well .…”

“…The processing of stimuli conforming to a regularity established by the immediate auditory history has also been investigated by Schadow et al (2009). However, they used an abstract regularity (instead of the repetition of a specific frequency), and they measured oscillatory activity in the gamma band as an additional variable.…”

“…The regularity should be established more firmly in later positions within the sequence than in earlier positions. If the RP is based on prediction and not on simple stimulus repetition effects (e.g., increased refractoriness of frequency-specific neurons), it should be observed in the design of Schadow et al (2009) as well. Although no explicit analysis was carried out by the authors, a comparison of the ERPs elicited by regularity-conforming tones in positions 3 and 5 of the sequence shows clear signs of RP (see Fig.…”

“…These cortices process auditory information and are thought to function as a "semantic processor" to deduce the meaning of sounds via learning [50]. In these cortices, sensory bottom-up and attentional top-down processing are closely related [51,52]; therefore, in young children, dysfunction in this central system is thought to underlie various learning problems [53,54]. In the present study, although no children exhibited hearing loss, there were weak correlations Table 2.…”

Autism spectrum disorder (ASD) has been postulated to involve impaired neuronal cooperation in large-scale neural networks, including cortico-cortical interhemispheric circuitry. In the context of ASD, alterations in both peripheral and central auditory processes have also attracted a great deal of interest because these changes appear to represent pathophysiological processes; therefore, many prior studies have focused on atypical auditory responses in ASD. The auditory evoked field (AEF), recorded by magnetoencephalography, and the synchronization of these processes between right and left hemispheres was recently suggested to reflect various cognitive abilities in children. However, to date, no previous study has focused on AEF synchronization in ASD subjects. To assess global coordination across spatially distributed brain regions, the analysis of Omega complexity from multichannel neurophysiological data was proposed. Using Omega complexity analysis, we investigated the global coordination of AEFs in 3-8-year-old typically developing (TD) children (n = 50) and children with ASD (n = 50) in 50-ms time-windows. Children with ASD displayed significantly higher Omega complexities compared with TD children in the timewindow of 0-50 ms, suggesting lower whole brain synchronization in the early stage of the P1m component. When we analyzed the left and right hemispheres separately, no significant differences in any time-windows were observed. These results suggest lower right-left hemispheric synchronization in children with ASD compared with TD children. Our study provides new evidence of aberrant neural synchronization in young children with ASD by investigating auditory evoked neural responses to the human voice.

The P1m component of the auditory evoked magnetic field is the earliest cortical response associated with language acquisition. However, the growth curve of the P1m component is unknown in both typically developing (TD) and atypically developing children. The aim of this study is to clarify the developmental pattern of this component when evoked by binaural human voice stimulation using child-customized magnetoencephalography. A total of 35 young TD children (32-121 months of age) and 35 children with autism spectrum disorder (ASD) (38-111 months of age) participated in this study. This is the first report to demonstrate an inverted U-shaped growth curve for the P1m dipole intensity in the left hemisphere in TD children. In addition, our results revealed a more diversified age-related distribution of auditory brain responses in 3- to 9-year-old children with ASD. These results demonstrate the diversified growth curve of the P1m component in ASD during young childhood, which is a crucial period for first language acquisition.
