概括

双向耳植入物 (CIs) 显示,对于儿童的言语感知,前额皮质激活更大. 虽然单边和双边的CI也会激活大脑,但双模刺激为听力康复提供了最大的听力益处.

科学领域:

神经科学是一个神经科学.
听力学听力学是指听力学.
语音语言病理学语言病理学

背景情况:

耳植入物 (CIs) 有助于聋子儿童的听力恢复和听力皮层成熟.
听力康复器件的类型可能会影响听力康复的结果.
在使用不同设备的普通话儿科CI用户中进行中央听觉处理需要进行调查.

研究的目的:

调查儿童CI接受者在语音感知过程中中央听觉处理激活模式.
基于CI设备特征 (单边,双边,双模) 的大脑活动差异进行比较.
分析对普通话语语音刺激的不匹配负面性 (MMN) 反应.

主要方法:

开发了一种多功能普通话发音范式,以引起MMN响应.
使用解剖自动标记 (AAL) 模板分析了MMN的皮层处理来源.
记录了临床特征,辅助听力值 (AHT) 和语音感知精度 (SPA).

主要成果:

32名儿科IC接受者 (12个单边,10个双边,10个双模) 参与了这项研究.
前额叶显示出最大的MMN活性,特别是在双模刺激中.
在CI类型之间发现了显著的前额外大脑皮层激活差异,主要是在上额外回环中.

结论:

建议进行双模体刺激,以最大限度地提高听觉效益.
双边植入对于没有残留听力的聋子儿童来说是最佳的.
单边植入比以前假设的更不有害,早期干预和培训可以弥补局限性.

The Cochlea

The Cochlea

The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Hearing

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.
