Abstract

Visual stimulation can generate illusory self-motion perception (vection) and cause motion sickness among susceptible people, but the underlying neural mechanism is not fully understood. In this study, SSVEP responses to visual stimuli presented in different parts of the visual field are examined in individuals with different susceptibilities to motion sickness to identify correlates of motion sickness. Alpha band SSVEP data were collected from fifteen university students when they were watching roll-vection-inducing visual stimulation containing: (1) an achromatic checkerboard flickering at 8.6 Hz in the central visual field (CVF) and (2) rotating dots pattern flickering at 12 Hz in the peripheral visual field. Rotating visual stimuli provoked explicit roll-vection perception in all participants. The motion sickness resistant participants showed reduced SSVEP response to CVF checkerboard during vection, while the motion sickness susceptible participants showed increased SSVEP response. The changes of SSVEP in the presence of vection significantly correlated with individual motion sickness susceptibility and rated scores on simulator sickness symptoms. Discussion on how the findings can support the sensory conflict theory is presented. Results offer a new perspective on vection and motion sickness susceptibility.

运动病抵抗者在矢量诱导刺激下表现出抑制稳态视觉诱发电位(SSVEP)
视觉刺激会产生虚幻的自我运动知觉(vection),并导致易感人群晕动病,但其潜在的神经机制尚未完全明了。在本研究中,我们研究了不同晕动病易感人群对呈现在视野不同部位的视觉刺激的 SSVEP 反应,以确定晕动病的相关因素。研究人员收集了 15 名大学生在观看滚动引力视觉刺激时的α波段 SSVEP 数据,这些视觉刺激包括:(1)在中央视野(CVF)中以 8.6 Hz 频率闪烁的消色差棋盘;(2)在周边视野中以 12 Hz 频率闪烁的旋转点图案。旋转视觉刺激在所有受试者中都能引起明确的滚动牵引感知。有晕动病的参与者在卷动过程中对 CVF棋盘的 SSVEP 反应减弱,而有晕动病的参与者对 CVF棋盘的 SSVEP 反应增强。出现脉动时 SSVEP 的变化与个人晕动病易感性和模拟器晕动病症状的评分有显著相关性。本文讨论了研究结果如何支持感觉冲突理论。研究结果为我们提供了一个新的视角来看待运动障碍和晕动病易感性:在线版本包含补充材料,可在 10.1007/s11571-023-09991-7上查阅。
