概括

与正常听力同龄人相比,带有耳植入器 (CI) 的语言前失聪儿童显示出对元音和辅音的听觉处理,但与正常听力同龄人相比,还没有成熟的词汇音调歧视. 长期使用CI可以改善听觉和语音表现.

科学领域:

听觉神经科学听觉神经科学
语音感知语音感知
神经生理学神经生理学

背景情况:

早期的听觉歧视对于语言发育至关重要.
耳植入物 (CI) 的目的是恢复聋人个体的听力.
了解CI用户的听觉处理对于优化康复至关重要.

研究的目的:

为了评估早期的语音特征的听觉歧视在CI的语言前聋子儿童.
为了比较CI用户和正常听力 (NH) 儿童之间的听觉事件相关潜力 (ERP).
为了研究CI使用时间和听觉表现之间的关系.

主要方法:

利用一个多偏差异奇怪的范式与单音节刺激.
记录的听觉事件相关潜力 (ERP),包括不匹配负面 (MMN) 和P3a响应.
分析了ERP,theta振荡同步,以及听觉性能得分 (CAP,SIR,MAIS).

主要成果:

NH儿童表现出强大的MMN对元音,辅音和词汇音调的对比.
CI儿童对元音和辅音对比显示了积极的不匹配响应 (pMMRs) 和P3a,但不是词汇音调.
CI儿童的pMMR/P3a延迟时间较长,theta同步较弱;较长的CI使用与更好的听觉表现相关.

结论:

在语言前失聪的CI儿童表现出声母和辅音的早期处理.
与NH同行相比,CI用户的词汇音调处理在CI用户中仍然不成熟.
ERP作为听觉语音功能成熟度的客观指标;长期使用CI是有益的.

Auditory Pathway

Auditory Pathway

Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking...

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
