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.

科学领域:

听觉神经科学听觉神经科学
比较的精神声学比较的精神声学
哺乳动物听力哺乳动物听力

背景情况:

人类听觉的频率调是有争议的,有声称比动物模型更清晰的调.
以前的研究表明,比猫有更敏的听觉神经调,但使用的方法有限.
音调值调整曲线可能会高估频率选择性,因为耳非线性.

研究的目的:

用宽带超值刺激测量的听觉神经中的光谱过.
为了比较和猫听觉神经纤维之间的频率选择性.
调查与动物模型相比,人类频率调更清晰的有争议的说法.

主要方法:

在麻醉的和猫中记录了单个听觉神经纤维反应.
使用宽带,多元组件刺激用于光谱过分析.
对近特征频率和低频尾的组延迟差异分析了相位数据.

主要成果:

听觉神经过器显示,与猫相比,的听觉神经过器趋向于更清晰的调,特别是在基底里.
定量差异比使用音色值数据的先前研究要小.
阶段数据支持的基底囊中的更清晰的频率调.

结论:

宽带超值刺激证实的听觉神经纤维的频率选择性比猫的频率选择性更强.
观察到的调清晰度差异不如基于音色值的数据所表明的那么明显.
这项研究为理解人类听力相对于非人类灵长类动物模型提供了关键数据.
