背景情况:

视听 (AV) 整合性,即"整合效应",影响视觉字母和语音的整合,这对阅读能力至关重要.
了解这种效应背后的神经振荡对于破译阅读发展至关重要.

研究的目的:

在视听字母-语音声音 (L-SS) 集成过程中调查和β频段的皮质振荡.
为了区分和β振荡在处理一致与不一致的L-SS对中的作用.

主要方法:

采用了日本的初始化任务,呈现了视觉字母,随后是语音声音.
分析的重点是theta (5-7 Hz) 和beta (20-35 Hz) 波段振荡的功率和相位特性.
审计相关区域的试验间阶段一致性 (ITPC) 被检查.

主要成果:

一致的L-SS对显示出在听觉皮层增加了达频段功率和跨模态相位重置.
在听觉区域增强的theta ITPC表明视觉字母可以放大对一致语音响应的响应.
在对等对的右侧中心平行体区域观察到降低的β带功率,这可能与听觉预测有关.

Perception of Sound Waves

Perception of Sound Waves

The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...

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.
