“…We calculated changes in the concentrations of oxy-Hb and deoxy-Hb, which were estimated based on the change in absorbance by using laser beams of approximately 780 and 830 nm, sampled at 10 Hz. The raw data of oxy-and deoxy-Hb in each channel were high-pass filtered at 0.0143 Hz and low-pass filtered at 0.8 Hz to remove components arising from physiological signals (i.e., respiratory and cardiac activity) and body movements (Naoi et al, 2012;Taga et al, 2003). We excluded blocks with motion artifacts (signal variations greater than 2 standard deviations from the mean over 0.2 s).…”

“…In newborns, it was observed that different syllabic structures caused activation in the frontal and temporal regions 16 . These same regions are activated in response to the familiarity, in the recognition of the mother's voice 17 .…”

“…The brain hemodynamic responses were analyzed regarding the speech discrimination 16 , perception of phonological 16 and prosodic 15 contrasts, development of the hemispheric laterality for speech 15 and influence of the mother's voice in the speech recognition 17 . The main results showed that phonemic changes activate the inferior frontal and inferior parietal regions and right temporal region; and the activation mainly occurs in the right temporal region for prosodic contrasts 15 .…”

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.

“…Several studies have been carried out and all of them agree that motherese provides, very precociously, either newborns or some month of life babies with neural activation 29 . Research has found activation of frontal brain area as a response to motherese 30,31 . These observations indicate that motherese influences the cerebral functions of the babies, increasing the activities in these regions, drawing attention to potentially significant words.…”

Very young babies show very refined language skills being able to perceive many features in adult speech. The perception of the mother tongue is essential to language acquisition. This literature review deals with speech perception skills from children under one year of age. Therefore a literature search was performed in 7 databases, in English, French, Portuguese and Spanish, in the period of [2003][2004][2005][2006][2007][2008][2009][2010][2011][2012][2013][2014]. With this bibliographic research was possible to recognize how language acquisition occurs quickly, and that very young infants are able to use elaborate strategies to initiate such acquisition. Keywords: Child Development; Infant; Cognition; Speech Perception RESUMO Bebês muito jovens demonstram habilidades linguísticas bastante refinadas, sendo capazes de perceber várias características na fala do adulto. A percepção da língua materna é, pois, imprescindível para a aquisição da linguagem. Esta revisão de literatura trata das habilidades de percepção de fala dos bebês a partir do nascimento até um ano de idade. Para tanto, foi realizada a busca bibliográfica em 7 bases de dados, nos idiomas inglês, francês, português e espanhol, no período de 2007 a 2014. Com esse levantamento bibliográfico foi possível reconhecer como a aquisição da linguagem ocorre de forma rápida e que bebês bem jovens são capazes de utilizar estratégias elaboradas para iniciar tal aquisição.
