A slow oscillatory movement (SOM) has previously been discovered superimposed on the three well known components of fixational eye movements. The purpose of the present study was to explore the visual influence on the control mechanism of the SOM. Three tests with different fixation targets and backgrounds were prepared. The eye position during a fixation task on healthy test subjects has been recorded by the Chronos eye tracking device. The visual stimuli with no or less information triggered larger SOM amplitudes. None of the investigated conditions significantly influenced on SOM frequency.
先前已发现一种缓慢振荡运动（SOM）叠加在注视眼动的三个众所周知的组成部分上。本研究的目的是探讨视觉对SOM控制机制的影响。准备了三种具有不同注视目标和背景的测试。通过Chronos眼动追踪设备记录了健康测试对象在注视任务期间的眼睛位置。没有信息或信息较少的视觉刺激会引发更大的SOM振幅。所研究的条件均未对SOM频率产生显著影响。
