“…It has been suggested (Steinmann & Gutschalk, 2012; Stroganova et al, 2022) that the auditory SF captured by MEG/EEG reflects the activation of so-called non-synchronized neuronal populations that implement rate-based coding and maintain increased firing throughout the stimulation period. The neurons of this type are driven by certain perceptually salient features of a complex sound, such as pitch or spectral structure, and serve as ‘feature detectors’, performing temporal integration of information for higher-level processing (Walker et al, 2011; Wang, 2018; Wang et al, 2005).…”

“…First , the sustained shift of potential (in EEG) or magnetic field (in MEG) associated with the processing of pitch and formant structure may reflect an integrated phonological representation of a time-varying complex acoustic signal in the auditory cortex (discussed in (Stroganova et al, 2022)). Animal studies show that this integrated representation is carried out by a certain type of neuronal population in the auditory cortex - the so-called non-synchronized neurons (Lu, Liang, & Wang, 2001; Wang, 2007, 2018; Wang, Lu, Bendor, & Bartlett, 2008; Wang, Lu, Snider, & Liang, 2005).…”

“…Second , unlike the transient components of auditory ERP/ERF, SF has the same ‘negative’ polarity in children and adults (Stroganova et al, 2020) and is similarly enhanced in these age groups by sound periodicity and formant structure (Gutschalk & Uppenkamp, 2011; Stroganova et al, 2022). Therefore, shifts of sustained cortical source current induced in the auditory cortex by these stimuli can be directly compared between age groups.…”

The spectral formant structure and periodicity pitch are the major features that determine the identity of vowels and the characteristics of the speaker. However, very little is known about how the processing of these features in the auditory cortex changes during development. To address this question, we independently manipulated the periodicity and formant structure of vowels while measuring auditory cortex responses using MEG in children aged 7-12 years and adults. We analyzed the sustained negative shift of source current associated with these vowel properties, which was present in the auditory cortex in both age groups despite differences in the transient components of the auditory response. In adults, the sustained activation associated with formant structure was lateralized to the left hemisphere early in the auditory processing stream requiring neither attention nor semantic mapping. This lateralization was not yet established in children, in whom the right hemisphere contribution to formant processing was strong and decreased during or after puberty. In contrast to the formant structure, periodicity was associated with a greater response in the right hemisphere in both children and adults. These findings suggest that left-lateralization for the automatic processing of vowel formant structure emerges relatively late in ontogenesis and pose a serious challenge to current theories of hemispheric specialization for speech processing.

“…This SF, captured by MEG/EEG, is thought to reflect the activation of non-synchronized neuronal populations [86,87]. These neurons function as 'feature detectors' for perceptually salient features of complex sounds, facilitating higher-level processing [88][89][90]. The enhancement of MEG/ EEG-measured SF occurs when stimuli are perceptually salient [91] or carry semantic meaning [92], and its magnitude varies with phonetic features, such as periodic versus non-periodic vowels [85].…”

In previous magnetoencephalography (MEG) studies, children with autism spectrum disorder (ASD) have been shown to respond differently to speech stimuli than typically developing (TD) children. Quantitative evaluation of this difference in responsiveness may support early diagnosis and intervention for ASD. The objective of this research is to investigate the relationship between syllable-induced P1m and social impairment in children with ASD and TD children. We analyzed 49 children with ASD aged 40–92 months and age-matched 26 TD children. We evaluated their social impairment by means of the Social Responsiveness Scale (SRS) and their intelligence ability using the Kaufman Assessment Battery for Children (K-ABC). Multiple regression analysis with SRS score as the dependent variable and syllable-induced P1m latency or intensity and intelligence ability as explanatory variables revealed that SRS score was associated with syllable-induced P1m latency in the left hemisphere only in the TD group and not in the ASD group. A second finding was that increased leftward-lateralization of intensity was correlated with higher SRS scores only in the ASD group. These results provide valuable insights but also highlight the intricate nature of neural mechanisms and their relationship with autistic traits.
