- 听觉神经科学 听觉神经科学
- 临床听力学 临床听力学
- 神经科学是一个神经科学.
背景情况:
- 之前对 tinnitus 患者倾听力度的研究显示正常听力值,但没有探索外周听力功能障碍.
- 周围听力功能障碍可能会影响中央听力系统,甚至在正常听力值的情况下也会增加倾听力度.
研究的目的:
- 为了研究 tinnitus 患者的听力努力,同时控制外周听力功能 (PAF).
- 用电脑脑图 (EEG) 来比较慢性耳患者和健康对照者的听力.
主要方法:
- 16名慢性耳患者和23名正常听力值的健康对照参与了这项研究.
- 评估包括纯色音计,VAS,MoCA,THI,矩阵测试,听觉脑干响应 (ABR) 和 parietal 电极的EEG α 波段活动.
主要成果:
- 与对照组相比,声患者在句子编码过程中表现出EEGα频段功率增加的减少.
- 耳参与者报告说,听力努力的视觉模拟量表 (VAS) 得分更高.

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.

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
