概括
无线电耳朵B81骨震动器可以有效地引起眼睛前庭引起的肌能潜能 (oVEMPs),与Brüel & Kjær迷你震动器相比. 这一发现支持了B81的发现.
科学领域:
- 静脉系统研究研究
- 听觉和前置器唤起了潜在的潜能.
背景情况:
- 有限证据表明,听力测量骨振动器可以引起眼前庭唤起肌能潜能 (oVEMPs).
- 之前的设备,如Brüel & Kjær Mini-shaker 4810,由于RadioEar B71的输出功率不足而成为必要的.
- 新的RadioEar B81模型显示了对oVEMP诱导的混合结果,可能是由于超出输出功率的因素,例如静态力应用.
研究的目的:
- 测试RadioEar B81骨震动器是否可以产生与Brüel & Kjær迷你摇器相当的骨导电oVEMP.
- 调查匹配的输出级别和足够的静态力在实现oVEMP等价性方面的作用.
主要方法:
- 用一个在组内平衡的设计来记录由两种传感器引起的oVEMP.
- 16名健康成年人参与了这项研究.
- 一个循环交替的500赫兹音频爆发刺激被传递到乳头,与相匹配的振动力水平 (127dB峰值相当) 和大约10N静态力. oVEMP波形从相反的眼睛记录下来.
主要成果:
- 在B81和Mini-shaker引起的oVEMP之间,在N10和N10-P15振幅上没有发现统计学上显著的差异.
- 在两种传感器之间,oVEMP的幅度和延迟在统计学上是相当的.
结论:
- 无线电耳朵B81可以引起oVEMPs与Mini-shaker相比没有任何有意义的区别,当刺激水平相匹配并施加足够的静态力时.
- 这些发现支持在临床环境中使用B81来在乳头上引起500Hz的oVEMP.
- 需要进一步的研究来探索不同频率和刺激地点的等价性.

The Vestibular System
39.4K
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.

The Auditory Ossicles
1.6K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

The Cochlea
44.6K
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.

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
