为了评价前庭视觉冲突(VVC)诱发的自主神经反应的动态变化，我们分析了松鼠唾液量和钠浓度的变化，以及R-R间期(RRI)在螺距平面上随VVC暴露时间的变化。钠浓度和唾液量在第1和第2个15min刺激期均有明显增加。RRI的变异系数在整个刺激期均呈上升趋势，静止值与刺激期相比有显著差异。RRI的变异系数与唾液量呈高度正相关。这些结果表明，在VVC期间存在一种共同的自主神经反应模式，并表明这些指标对于客观监测运动病的严重程度是有用的。
To assess the dynamic changes of the autonomic neural responses evoked by vestibular-visual conflict (VVC) in the squirrel monkey, we analyzed the changes of salivary amount and sodium concentration, and the coefficient of variance (CV) of R-R intervals (RRI) along the time course of VVC exposure given in pitch plane. The sodium concentration and the amount of saliva showed clear increases at the first and second 15 min stimulation periods. The CV of RRI was found to increase over the entire periods of stimulation, and there was a significant difference between the rest value and those in stimulated periods. The correlation between the CV of RRI, and amount of salivation was highly positive. These results indicate the existence of a common pattern of autonomic neural response during VVC, and suggest usefulness of these indexes for objectively monitoring the severity of motion sickness.
