“…Although the auditory cortex decodes fast acoustic modulations, relevant for the phonemic decoding within the speech flow in a bilateral way, the phonemic contrasts preferentially activate the left hemisphere of the temporal region in babies. The prosodic contrasts predominantly activated the right temporal region 10,15,21,22 . Reinforcing the role of this region for the sensory processing of emotional speech signals.…”

Purpose: to systematically review, through the search in the Medline and Lilacs database, the use of near-infrared spectroscopy (NIRS) as a tool to evaluate the auditory function at the cortical level in infants. Methods: integrative review based on the criteria established by the Cochrane Handbook including the definition of the guiding question (theme to be researched), definition of the database to locate the articles, and selection and critical analysis of the articles. The bibliographic search was performed from September to December 2014. The inclusion criteria were: articles published in English, Portuguese and Spanish related to the child population (infants aged from 0 to 24 months) and type of study (cohort, case-control, cross-sectional).Results: 1674 articles were identified and 12 met the inclusion criteria of this study. In all articles, the auditory stimulation was used to measure brain hemodynamic changes, but in different areas of interest of the brain. They were grouped into three categories according to the type of stimulus: only vocal sounds, vocal sounds and other auditory stimuli and non-vocal sounds. Conclusion: NIRS is an effective tool for the evaluation of the auditory function at the cortical level in the child population. Keywords: Spectroscopy, Near-Infrared; Hemodynamics; Auditory Perception; Hearing; Central Nervous System RESUMO Objetivo: revisar sistematicamente, por meio de busca nas plataformas Medline e Lilacs o uso da espectroscopia de luz próxima ao infravermelho (NIRS) como instrumento para a avaliação da audição a nível cortical em lactentes. Métodos: foi realizada uma revisão integrativa baseada nos critérios estabelecidos pela Cochrane Handbook, passando pelas etapas de definição da questão norteadora (o tema a ser pesquisado), definição das bases de dados para localização dos estudos, seleção e análise crítica dos artigos. A pesquisa bibliográfica foi realizada no período de setembro a dezembro de 2014. Os critérios de inclusão utilizados foram: artigos publicados nos idiomas inglês, português e espanhol, com a população infantil (bebês de 0 a 24 meses) e tipo de estudo (coorte, caso controle, transversal). Resultados: foram identificados 1674 artigos e 12 atenderam os critérios de inclusão deste estudo. Todos os artigos utilizaram o estímulo auditivo para medir alterações na hemodinâmica cerebral, porém com áreas cerebrais de interesse diferentes. E foram agrupados em três categorias quanto ao tipo de estímulo: apenas sons vocais, sons vocais e outros estímulos auditivos e sons não vocais. Conclusão: a NIRS é um instrumento eficaz para investigação da audição a nível cortical na população infantil.

“…However, adults have extensive experience with language, leaving open the issue of causation. Telkemeyer et al (2011), Arimitsu et al (2011), andMinagawa-Kawai et al (2011) now test these hypotheses on newborns and young infants using different temporally and spectrally modulated tone stimuli, asking whether the observed hemispheric specializations are the causes or the results of lateralized language processing. As an innovative extension of the research on early brain specialization for speech, Sato et al (2011) investigate whether, and if yes, how this specialization might be different in an atypical population, stuttering children and adults.…”

“…May et al (2011) compare newborn infants' brain responses to the native language, spoken by the mother during pregnancy, and to an unknown language, in an attempt to investigate how prenatal experience with speech might shape the brain specialization for language. Telkemeyer et al (2011), Arimitsu et al (2011) as well as Minagawa-Kawai et al (2011) take a different approach, seeking to identify the acoustic, spectrotemporal properties of the speech signal might underlie brain specialization. In adults, it has been shown that fast-changing sounds or sounds modulated in time preferentially recruit areas in the left hemisphere that are part of the language network, while slowly changing sounds or sounds modulated spectrally tend to engage the right hemisphere (Zatorre et al, 2002;Hickok and Poeppel, 2007).…”

Edited and reviewed by: Manuel Carreiras, Basque Center on Cognition, Brain and Language, SpainKeywords: language learning, language developmental, speech perception, brain specialization for language, near-infrared spectroscopy, developmental cognitive neuroscience Near-Infrared Spectroscopy (NIRS) is a relatively novel and increasingly popular optical imaging technique that has revolutionized brain research in the developmental populations (Villringer and Chance, 1997;Lloyd-Fox et al., 2009;Gervain et al., 2011). After more than a decade of technological development, NIRS has become a reliable, easy-to-use and efficient tool to explore the linguistic and cognitive abilities of neonates and young infants, opening new vistas for the investigation of language acquisition and cognitive development. This Research Topic covers the latest advances in these areas brought about by NIRS imaging. The main focus is to highlight innovative and foundational studies that go beyond methodological issues and advance our theoretical understanding of infant and child development. Contributions from the pioneers of this method are selected, illustrating how NIRS has allowed developmental researchers to ask theoretically relevant questions that more traditional methods couldn't address.The first two contributions, by Fava et al. (2011) and Benavides-Varela et al. (2011), cover general theoretical issues and methodological principles. They provide a critical, but constructive overview of theoretical questions about linguistic and cognitive development that have been asked, outline challenges that the NIRS community still needs to face and offer recommendations for optimal experimental designs and data interpretations practices. These general contributions are followed by a series of empirical papers exploring a key issue in the study of the neural correlates of language learning and development, the nature and origins of the brain specialization for speech and language. While it is well established that in the majority of right-handed adults, language is preferentially processed in the left hemisphere (e.g., Friederici, 2005), the reasons for and the ontogenetic origins of this left lateralization have so far been less well understood, partly because the field lacked a safe, fully non-invasive, participantfriendly brain imaging method with which to probe the infant brain. NIRS has filled this gap, opening up the way for exciting new discoveries about the brain specialization for speech and language in young babies (e.g

Does cerebral lateralization develop? A study using functional transcranial Doppler ultrasound assessing lateralization for language production and visuospatial memory

et al. 2012

In the majority of people, language production is lateralized to the left cerebral hemisphere and visuospatial skills to the right. However, questions remain as to when, how, and why humans arrive at this division of labor. In this study, we assessed cerebral lateralization for language production and for visuospatial memory using functional transcranial Doppler ultrasound in a group of 60 typically developing children between the ages of six and 16 years. The typical pattern of left-lateralized activation for language production and right-lateralized activation for visuospatial memory was found in the majority of the children (58%). No age-related change in direction or strength of lateralization was found for language production. In contrast, the strength of lateralization (independent of direction) for visuospatial memory function continued to increase with age. In addition, boys showed a trend for stronger right-hemisphere lateralization for visuospatial memory than girls, but there was no gender effect on language laterality. We tested whether having language and visuospatial functions in the same hemisphere was associated with poor cognitive performance and found no evidence for this “functional crowding” hypothesis. We did, however, find that children with left-lateralized language production had higher vocabulary and nonword reading age-adjusted standard scores than other children, regardless of the laterality of visuospatial memory. Thus, a link between language function and left-hemisphere lateralization exists, and cannot be explained in terms of maturational change.
