本研究的目的是澄清在脑电图（EEG）活动模式的差异，在眼睛运动所需的跟踪可见和闭塞的移动目标与毫秒时间resolution.MethodsTo实现这一目标，我们同时测量EEG和眼睛跟踪在一个任务，需要跟踪移动目标，部分被遮挡。这些EEG和眼动仪参数进行了比较与nonoccluded的任务，一个控制任务，其中移动的目标是完全visible. ResultsEEG活动模式在顶叶眼场和后顶叶的差异，观察在闭塞的部分在闭塞的任务与nonoccluded的任务相比。在相同的条件下，在中颞视觉区，后顶叶，前运动，初级运动皮层，颞叶的EEG活动模式的差异，观察在可见的部分在闭塞task.ConclusionThese结果表明，闭塞的存在影响EEG活动模式，不仅当目标是闭塞，但也立即闭塞前。
ObjectiveThe objective of this study was to clarify the differences in electroencephalogram (EEG) activity patterns during the eye movements required to trace visible and occluded moving targets with millisecond temporal resolution.MethodsTo achieve this objective, we simultaneously measured EEG and eye-tracking during a task that required tracking moving targets that were partially occluded. These EEG and eye tracker parameters were compared with those of a nonoccluded task, a control task in which the moving target was fully visible.ResultsDifferences in EEG activity patterns in the parietal eye field and posterior parietal lobe were observed during the occluded sections in the occluded task compared with the nonoccluded task. Under the same conditions, differences in EEG activity patterns in the middle temporal visual area, posterior parietal lobe, premotor, primary motor cortex, and temporal lobe were observed during visible sections in the occluded task compared with the nonoccluded task.ConclusionThese results indicate that the presence of occlusion affects EEG activity patterns not only when the target is occluded but also immediately before occlusion.
