- 刺激类型可以影响cVEMP特征.
研究的目的:
- 通过音频爆发 (TB) 引起的cVEMP与狭窄频段水平特定的声 (NB LS-CE Chirp) 刺激进行比较.
- 在健康个体中评估500,1,000,2000和4000赫兹的刺激.
主要方法:
- 32名健康参与者接受了cVEMP测试.
- 刺激包括结核病和NB LS-CE Chirp在95dB nHL.
- 记录了P1延迟,N1延迟和P1N1振幅.
主要成果:
- 在所有受试者中,这两种刺激都在500 Hz时引起了反应.
- 在500和1,000 Hz (p <0.05) 时观察到P1延迟,N1延迟和P1N1振幅的显著差异.

The Vestibular System
43.3K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Equilibrium and Balance
6.2K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

The Cochlea
50.4K
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.

Muscle Stimulation Frequency
4.3K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.
