概括

异常性耳患者在特定频率上表现出增强的听觉稳定状态响应 (ASSR),这表明更高的听觉区域的感觉处理发生了变化. 这表明听觉通路的潜在双边参与,即使局部耳.

科学领域:

神经科学是一个神经科学.
听觉神经科学听觉神经科学
临床听力学临床听力学

背景情况:

异常性耳是一种常见的听觉障碍,通常与潜在的神经变化有关.
审计稳定状态响应 (ASSR) 提供了审计通路功能的客观测量.

研究的目的:

用ASSR. 调查异常性耳患者的听觉处理中的改变.
为了比较耳患者和健康对照者之间的ASSR特征.

主要方法:

使用了多个ASSR,其调制频率为20,40和80 Hz.
在19名耳患者和24名对照人群中比较了稳定状态反应和值.
检查了与耳相对的ipsilateral和contralateral反应.

主要成果:

在耳患者的ipsilateral和contralateral侧之间没有发现ASSR值的显著差异.
与对照组相比,在患有特异性耳患者的40 Hz和80 Hz调制频率下观察到增强的ASSR.
这些发现表明,高阶听觉区域的神经活动发生了变化.

结论:

这项研究表明,在患有特异性耳的个体中,更高级的听觉区域可能存在感官缺陷.
结果表明,听觉通路的双边参与,即使在侧向耳的情况下.

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.
