“…It is possible that by using hemodynamic techniques (fNIRS and fMRI) we have tapped into this second, higher‐order process of temporal signal integration within the left hemisphere. Taken together, this evidence suggests that the left‐hemisphere sensitivity to a narrow range of slow temporal modulations might play a significant role in successful language and reading acquisition …”

“…extends beyond the auditory modality and suggests that subcortical brain regions (i.e., cerebellum, basal ganglia, and thalamus) are sensitive to both visual and auditory sources of temporal information, which are then relayed to language‐related cortical regions. Such a model helps explain convergent findings for our studies that aimed to tap into early language acquisition processes across natural sign and spoken languages …”

“…suggest that a child's left hemisphere might play an important role in her/his ability to preferentially tune to temporal information linked to the first milestones of language and reading acquisition . Second, Ugolini et al . demonstrate that variations in children's language and reading ability might be linked to left‐hemisphere sensitivity to slow temporal modulations.…”

New approaches to understanding language and reading acquisition propose that the human brain's ability to synchronize its neural firing rate to syllable-length linguistic units may be important to children's ability to acquire human language. Yet, little evidence from brain imaging studies has been available to support this proposal. Here, we summarize three recent brain imaging (functional near-infrared spectroscopy (fNIRS), functional magnetic resonance imaging (fMRI), and magnetoencephalography (MEG)) studies from our laboratories with young English-speaking children (aged 6-12 years). In the first study (fNIRS), we used an auditory beat perception task to show that, in children, the left superior temporal gyrus (STG) responds preferentially to rhythmic beats at 1.5 Hz. In the second study (fMRI), we found correlations between children's amplitude rise-time sensitivity, phonological awareness, and brain activation in the left STG. In the third study (MEG), typically developing children outperformed children with autism spectrum disorder in extracting words from rhythmically rich foreign speech and displayed different brain activation during the learning phase. The overall findings suggest that the efficiency with which left temporal regions process slow temporal (rhythmic) information may be important for gains in language and reading proficiency. These findings carry implications for better understanding of the brain's mechanisms that support language and reading acquisition during both typical and atypical development.

“…PWM and PA skills are positively related to auditory processing skills since, in order to process the sounds of speech phonologically it is first necessary to interpret them 37,38 . The auditory pathways of children with a history of undernutrition exhibit a delay in the myelinization process of the auditory pathways.…”

Purpose: to determine whether undernutrition in the first years of life affects the phonological awareness skills, the phonological working memory and the school performance of children. Methods: the participants were children with a history of moderate/severe undernutrition during their first years of life (G1) who achieved nutritional recovery (n = 15). The performance of G1 in different cognitive tasks (phonological awareness at the syllable and phoneme level, phonological working memory - repetition of digits and pseudowords, and reading, writing and arithmetic activities) was compared to that of children with school difficulties (G2) (n = 15) and without school difficulties (G3) (n = 15), all eutrophic ones. Results: the performance of G1 was worse than that of the other two groups in all tasks evaluated (mean score of G1, G2 and G3 and p-values: phonological awareness: 31, 41, 57 - 0.01; repetition of direct order digits: 18, 23, 28 - 0.001; writing: 4, 10, 22 - 0.001; reading: 26, 45, 65-0.001; arithmetic: 4, 7, 11- 0.001). Conclusion: the results demonstrate that undernutrition affected the cognitive development, causing changes in important cognitive skills for the development of written language.
