摘要

导言:功能性近红外光光谱(fNIRS)可用于研究儿童的大脑皮层反应,并能帮助人们深入了解生命早期阶段的听觉和语言感知能力。一些文献表明,婴儿一出生就能识别熟悉的声音,而 fNIRS 是一种非侵入性技术,可用于研究这一人群。目的 使用近红外光光谱分析婴儿出生后三个月内对婴儿引导的语音的皮层反应,并验证婴儿引导的语音由母亲发出时,婴儿的反应与由未知人发出时是否存在差异。方法 对 23 名 0 至 3 个月、健康、无听力损失风险指标且听力评估结果正常的儿童进行了近红外光光谱测试,将婴儿引导的语言作为听觉刺激,分别由其母亲和未知人士发出。结果 观察到双侧大脑皮层激活。反应出现在颞叶、额叶和顶叶区域。在熟悉程度方面,母亲的声音与未知声音没有明显差异。结论 在婴儿出生后的头三个月,婴儿引导的语音具有能够激活多个大脑皮层区域,尤其是颞叶区域的前音特征。在这一时期,需要更好地界定这类刺激的熟悉效应。

Cortical Responses to Mother's Voice in Comparison with Unfamiliar Voice in the First Trimester of Life: A fNIRS Study.

Introduction  The use of functional near-infrared light spectroscopy (fNIRS) may be applied to study cortical responses in children and could offer insight into auditory and speech perception during the early stages of life. Some literature suggests that babies are already able to identify familiar voices at birth, and fNIRS is a non-invasive technique that can be used to study this population. Objective  To characterize the cortical responses of infants during their first trimester of life to infant-directed speech using near-infrared light spectroscopy and to verify whether there is a difference in responses when infant-directed speech is performed by their mother compared with an unknown person. Methods  Twenty-three children between 0 and 3 months, healthy, without risk indicators for hearing loss, and with results considered normal in the audiological evaluation were tested with near-infrared spectroscopy using infant-directed speech as an auditory stimulus produced by their own mother and by an unknown source. Results  Bilateral cortical activation was observed. The responses were present in the temporal, frontal, and parietal regions. Regarding the familiarity aspect, no significant difference was observed for the mother's voice compared with an unknown voice. Conclusion  Infant-directed speech has prosodic characteristics capable of activating several cortical regions in the infant's first trimester of life, especially the temporal region. The familiarity effect needs to be better defined for this type of stimulus during this period.
