“…The bold red line is the regression line that corresponds to all data (i.e., the combination of the first and second measurements). by recent technical advancements (e.g., child custom-sized MEG), MEG is an excellent tool for investigating the spatio-temporal dynamics of neural activation associated with sensory perception in early childhood (Huotilainen et al, 2008;Pang, 2011). The component analyzed in our previous study was identical to P100m, M50 and P1m responses, which have been demonstrated in previous MEG studies (Oram Cardy et al, 2004;Orekhova et al, 2012;Pihko et al, 2007).…”

The relationship between language development in early childhood and the maturation of brain functions related to the human voice remains unclear. Because the development of the auditory system likely correlates with language development in young children, we investigated the relationship between the auditory evoked field (AEF) and language development using non-invasive child-customized magnetoencephalography (MEG) in a longitudinal design. Twenty typically developing children were recruited (aged 36-75 months old at the first measurement). These children were re-investigated 11-25 months after the first measurement. The AEF component P1m was examined to investigate the developmental changes in each participant's neural brain response to vocal stimuli. In addition, we examined the relationships between brain responses and language performance. P1m peak amplitude in response to vocal stimuli significantly increased in both hemispheres in the second measurement compared to the first measurement. However, no differences were observed in P1m latency. Notably, our results reveal that children with greater increases in P1m amplitude in the left hemisphere performed better on linguistic tests. Thus, our results indicate that P1m evoked by vocal stimuli is a neurophysiological marker for language development in young children. Additionally, MEG is a technique that can be used to investigate the maturation of the auditory cortex based on auditory evoked fields in young children. This study is the first to demonstrate a significant relationship between the development of the auditory processing system and the development of language abilities in young children.

“…Mäkelä et al, ). Few earlier studies have used source modeling algorithms to clarify the characteristics of the neural currents generating the auditory evoked responses in infants (Huotilainen, ; Ortiz‐Mantilla et al, ) and children (Orekhova et al, ; Paetau, Ahonen, Salonen, & Sams, ; Parviainen et al, ; Takeshita et al, ). Our present results are in line with those studies showing prominent long‐lasting activation in children, often termed N250(m).…”

Auditory cortex in each hemisphere shows preference to sounds from the opposite hemifield in the auditory space. Besides this contralateral dominance, the auditory cortex shows functional and structural lateralization, presumably influencing the features of subsequent auditory processing. Children have been shown to differ from adults in the hemispheric balance of activation in higher‐order auditory based tasks. We studied, first, whether the contralateral dominance can be detected in 7‐ to 8‐year‐old children and, second, whether the response properties of auditory cortex in children differ between hemispheres. Magnetoencephalography (MEG) responses to simple tones revealed adult‐like contralateral preference that was, however, extended in time in children. Moreover, we found stronger emphasis towards mature response properties in the right than left hemisphere, pointing to faster maturation of the right‐hemisphere auditory cortex. The activation strength of the child‐typical prolonged response was significantly decreased with age, within the narrow age‐range of the studied child population. Our results demonstrate that although the spatial sensitivity to the opposite hemifield has emerged by 7 years of age, the population‐level neurophysiological response shows salient immature features, manifested particularly in the left hemisphere. The observed functional differences between hemispheres may influence higher‐level processing stages, for example, in language function.

If the brain structural coordinates could be estimated using the individual head shape, magnetoencephalography and near-infrared spectroscopy would be more ideal brain functional imaging methods especially for young human children. First, we propose an algorithm to estimate brain coordinates with reference to the head surface shape in preschool children. Second, we examined its spatial error range using a leave-one-out procedure within 38 samples of child head and brain structures. The mean error of landmarks was 13.6±5.3 mm on the head surface and 18.5±12.4 mm in the intracranial structure between estimated and actual brain coordinates.
