概括
小脑是小脑的组成部分.
科学领域:
- 神经科学是一个神经科学.
- 人类的空间导向 人类的空间导向
- 感官整合 感官整合
背景情况:
- 准确的重力感知需要整合视觉和前庭输入.
- 以前的研究暗示小脑的作用,但缺乏直接证据.
研究的目的:
- 为了研究大脑小虫在视觉前体相互作用中对重力感知的作用.
- 评估大脑小脑跨脑磁性刺激对视觉依赖的影响.
主要方法:
- 健康的参与者经历了反复的跨磁刺激 (rTMS) 在大脑后方的虫.
- 视觉依赖是通过旋转光动学刺激 (OKS) 诱导的主观视觉垂直 (SVV) 偏差来测量的.
- 电场模拟证实了焦点小脑刺激.
主要成果:
- 在小脑虫上进行的RTMS显著降低了OKS诱导的SVV偏差.
- 对视觉皮层或小脑半球的刺激没有产生相同的效果.

The Vestibular System
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.
Major Somatic Sensory Pathways
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
