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

本研究的目的是评估垂直半规管对眼倾斜反应（OTR）和主观视觉垂直（SVV）（例如空间参考和姿势）的影响。前庭音调不平衡，在滚动平面中诱发 OTR 和 SVV。 OTR 和 SVV 表示基于垂直半规管输入的协调眼头滚动运动的模式。关于这项研究。 OTR 和 SVV 是对侧（对侧眼在最下方）垂直（后）半规管兴奋时。当 OTR 和 SVV 发生时，会引起同侧滚动运动（与激发的垂直半规管方向相同）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感知相关性。滚动运动可能是对明显倾斜的视觉脊柱姿势补偿（OTR 和 SVVX 红外地形图研究，测量对周围前庭装置进行热量刺激期间的顶颞 CBF。相对双侧 CBF 因热水刺激而增加，但因冷水而减少。如果左右 GBF 之间的差异较强， 出现头晕现象。由周围前庭装置支配的顶颞叶皮层与空间方向有关。我得出结论，垂直半规管影响空间方向
