Influence of Vertical Semicircular Canals Qfl spatial reference and posture

本研究的目的是评价垂直半规管对眼球倾斜反应和主观视觉垂直(SVV)的影响，如空间参考和姿势。前庭张力失衡，在滚动面诱发OTR和SVV。OTR和SVV代表了基于垂直半规管输入的协调眼头滚动运动模式。关于这项研究。在垂直(后)半规管兴奋时，OTR和SVV是对比性的(对侧眼下方)。当OTR和SVV发生时，会诱发同侧的侧滚向量(与激发的垂直半圆管方向相同)和身体摇摆。SVV向Otr方向的倾斜表明，这是身体倾斜相对于真实地球坐标的知觉关联。翻滚可能是视觉脊髓姿势对表观倾斜的补偿(OTR和SVVX红外地形图研究，测量外周前庭装置在热量刺激时的顶颞部脑血流)。热水刺激可使相对双侧脑血流量增加，冷水刺激可使相对双侧脑血流量降低。如果。左右两侧GBF差异较大，出现眩晕。由外周前庭装置支配的顶颞叶皮质与空间方位有关。我认为垂直半规管影响空间方位

The aim of this study is to evaluate the influence of vertical semicircular canals on ocular tilt reaction (OTR) and subjective visual vertical (SVV) such as spatial reference, and posture. Vestibular tone imbalance, in the roll plane induces OTR and SVV. OTR and SVV represents a pattern of coordinated eye-head roll motion based vertical semicircular canal input. Regarding this study. OTR and SVV are contraversive (contralateral eye undermost) during the vertical (posterior) semicircular canal excited. Ipsilateral roll vection (same direction to the excited vertical semicirculau canal) and body sway are induced when OTR and SVV occur. The tilt of SVV toward the direction of OTR suggests that this is the perceptual correlation of body tilt relative to the true earth coordinates. Roll vection may be visuospinal postural compensation for the apparent tilts (OTR and SVVXInfra-red topography study, which measure the parieto-temporal CBF during caloric stimulus to the peripheral vestibular apparatus, is underwent. The relative bilateral CBF increase by hot water stimulus, but decrease by cold water. If the. difference between the right and the left GBF was stronger, dizziness was occurred. The parietotemporal cortex innervated from the peripheral vestibular apparatus relates to the spatial orientation.I conclude that vertical semicircular canal influences the spatial
