概括

下跳性阴影 (DBN) 不会随着头部在滚动平面上的倾斜而改变. 与对照组相比,患有DBN的患者在判断垂直性的变化更大.

科学领域:

神经科学是一个神经科学.
眼科医生眼科眼科
垂体系统垂体系统垂体系统

背景情况:

低节奏性鼻 (DBN) 是一种常见的获得性中枢前庭鼻的形式.
之前关于DBN和重力感知的研究集中在全身倾斜时的俯冲和滚动平面上.
滚动平面中头部倾斜对DBN和主观视觉垂直 (SVV) 的影响仍未得到充分研究.

研究的目的:

调查DBN患者在滚动平面中的静态和动态重感受功能.
为了评估主观视觉垂直 (SVV) 和缓慢相速 (SPV) 的调制 DBN 响应头部倾斜.
为了比较DBN患者与健康对照对滚动平面重感受.

主要方法:

在26名DBN患者和13名对照人群中评估了SVV和SPV调节.
被测试的参与者在滚动平面 (0°,30°顺时针方向,30°逆时针方向) 中处于不同的头部与干部倾斜位置.

主要成果:

DBN的SPV在滚动平面中的不同头部倾斜角度中没有显著的调制.
在DBN患者和对照人群中,SVV评级没有显著差异.
与对照组相比,DBN患者在平均SVV估计中表现出更高的变化.

结论:

与投球平面不同的是,DBN在滚球平面中不表现出调制.
患有DBN的患者在滚动平面垂直感知方面表现出更高的不确定性,由更高的响应可变性表明.

Equilibrium and Balance

Equilibrium and Balance

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 Vestibular System

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

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...
