Abstract

Introduction: Children with specific language impairment (SLI) have difficulties in different speech and language domains. Electrophysiological studies have documented that auditory processing in children with SLI is atypical and probably caused by delayed and abnormal auditory maturation. During the resting state, or different auditory tasks, children with SLI show low or high beta spectral power, which could be a clinical correlate for investigating brain rhythms.

Methods: The aim of this study was to examine the electrophysiological cortical activity of the beta rhythm while listening to words and nonwords in children with SLI in comparison to typical development (TD) children. The participants were 50 children with SLI, aged 4 and 5 years, and 50 age matched TD children. The children were divided into two subgroups according to age: (1) children 4 years of age; (2) children 5 years of age.

Results: The older group differed from the younger group in beta auditory processing, with increased values of beta spectral power in the right frontal, temporal, and parietal regions. In addition, children with SLI have higher beta spectral power than TD children in the bilateral temporal regions.

Conclusion: Complex beta auditory activation in TD and SLI children indicates the presence of early changes in functional brain connectivity.

有特殊语言障碍的学龄前儿童被动聆听时的β频谱功率

简介特殊语言障碍（SLI）儿童在不同的言语和语言领域都存在困难。电生理学研究表明，SLI 儿童的听觉处理能力不典型，可能是由于听觉成熟延迟和异常造成的。在静息状态或不同的听觉任务中，SLI 儿童表现出低或高β频谱功率，这可能是研究大脑节奏的临床相关因素：本研究旨在研究 SLI 儿童与典型发育（TD）儿童在听单词和非单词时的β节奏的电生理皮层活动。研究对象包括 50 名 4 至 5 岁的 SLI 儿童和 50 名年龄相仿的 TD 儿童。根据年龄将儿童分为两组：1）4 岁儿童；2）5 岁儿童：结果显示：大龄组与小龄组在贝塔听觉处理方面存在差异，右侧额叶、颞叶和顶叶区域的贝塔频谱功率值增加。此外，在双侧颞叶区域，SLI 儿童的 beta 频谱功率高于 TD 儿童：结论：TD 和 SLI 儿童复杂的 beta 听觉激活表明大脑功能连接存在早期变化。

期刊介绍： ''Developmental Neuroscience'' is a multidisciplinary journal publishing papers covering all stages of invertebrate, vertebrate and human brain development. Emphasis is placed on publishing fundamental as well as translational studies that contribute to our understanding of mechanisms of normal development as well as genetic and environmental causes of abnormal brain development. The journal thus provides valuable information for both physicians and biologists. To meet the rapidly expanding information needs of its readers, the journal combines original papers that report on progress and advances in developmental neuroscience with concise mini-reviews that provide a timely overview of key topics, new insights and ongoing controversies. The editorial standards of ''Developmental Neuroscience'' are high. We are committed to publishing only high quality, complete papers that make significant contributions to the field.
