前言 在离心机旋转时,当面切向朝前直坐时,受试者感到横滚倾侧。这种感知到的倾侧取决于重力惯性力矢量的综合角。研究揭示受试者面朝前比朝后前庭性眼球震颤持续时间要长。我们比较了面朝前和朝后时感知地平线判断以及在这些朝向时自动感知的持续时间。方法 受试者(n=29)在黑暗中旋转,离心机半径为20英尺,产生重力惯性力矢量为45°或60°倾 Preface While the centrifuge is spinning, the subject feels roll-over while tangentially facing straight forward. This perceived tilt depends on the composite angle of gravity inertia force vector. The study revealed that the subjects were facing forward longer than retrograding nystagmus. We compare the perception of the horizon when facing forward and backward as well as the duration of auto-sensing in these orientations. Method Subjects (n = 29) were rotated in the dark with a centrifuge radius of 20 feet giving a vector of gravitational inertia of 45 ° or 60 °
