Abstract

To understand the consequences of prematurity on language perception, it is fundamental to determine how atypical early sensory experience affects brain development. At term equivalent age, ten preterm and ten full-term newborns underwent high-density EEG during mother or stranger speech presentation, in the forward or backward order. A general group effect terms > preterms is evident in the theta frequency band, in the left temporal area, with preterms showing significant activation for strangers’ and terms for the mother’s voice. A significant group contrast in the low and high theta in the right temporal regions indicates higher activations for the stranger's voice in preterms. Finally, only full terms presented a late gamma band increase for the maternal voice, indicating a more mature brain response.

EEG time–frequency analysis demonstrate that preterm infants are selectively responsive to stranger voices in both temporal hemispheres, and that they lack selective brain responses to their mother’s forward voice.

早产儿表现出对母亲声音的非典型处理。

为了理解早产对语言感知的影响，确定非典型的早期感觉体验如何影响大脑发育是至关重要的。在足月时，10名早产和10名足月新生儿在母亲或陌生人讲话时接受了高密度脑电图检查，检查顺序为前向或后向。在左颞区的θ频带中，一个普遍的群体效应项>前测项是明显的，前测项对陌生人的声音和母亲的声音表现出显著的激活。右颞区的低θ和高θ的显著组对比表明，在预测试中，陌生人的声音有更高的激活度。最后，只有完整的术语显示出母亲声音的晚期伽马带增加，表明大脑反应更加成熟。脑电图的时频分析表明，早产儿对两个颞半球的陌生声音都有选择性的反应，而他们对母亲的正向声音缺乏选择性的大脑反应。

期刊介绍： Brain and Cognition is a forum for the integration of the neurosciences and cognitive sciences. B&C publishes peer-reviewed research articles, theoretical papers, case histories that address important theoretical issues, and historical articles into the interaction between cognitive function and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in cognition. Coverage includes, but is not limited to memory, learning, emotion, perception, movement, music or praxis in relationship to brain structure or function. Published articles will typically address issues relating some aspect of cognitive function to its neurological substrates with clear theoretical import, formulating new hypotheses or refuting previously established hypotheses. Clinical papers are welcome if they raise issues of theoretical importance or concern and shed light on the interaction between brain function and cognitive function. We welcome review articles that clearly contribute a new perspective or integration, beyond summarizing the literature in the field; authors of review articles should make explicit where the contribution lies. We also welcome proposals for special issues on aspects of the relation between cognition and the structure and function of the nervous system. Such proposals can be made directly to the Editor-in-Chief from individuals interested in being guest editors for such collections.
