Human action control relies on event files, that is, short-term stimulus-response bindings that result from the integration of perception and action. The present EEG study examined oscillatory brain activities related to the integration and disintegration of event files in the distractor-response binding (DRB) task, which relies on a sequential prime-probe structure with orthogonal variation of distractor and response relations between prime and probe. Behavioral results indicated a DRB effect in RTs, which was moderated by the duration of the response-stimulus interval (RSI) between prime response and probe stimulus onset. Indeed, a DRB effect was observed for a short RSI of 500 msec but not for a longer RSI of 2000 msec, indicating disintegration of event files over time. EEG results revealed a positive correlation between individual DRB in the RSI-2000 condition and postmovement beta synchronization after both prime and probe responses. Beamformer analysis localized this correlation effect to the middle occipital gyrus, which also showed highest coherency with precentral and inferior parietal brain regions. Together, these findings suggest that postmovement beta synchronization is a marker of event file disintegration, with the left middle occipital gyrus being a hub region for stimulus-response bindings in the visual DRB task.

观察大脑（未）绑定：Beta 同步与干扰器响应绑定有关。

人类动作控制依赖于事件文件，即由感知和动作整合产生的短期刺激-反应绑定。目前的脑电图研究检查了与干扰物反应绑定 (DRB) 任务中事件文件的整合和分解相关的振荡大脑活动，该任务依赖于顺序主探针结构，干扰物正交变化以及主探针和探针之间的响应关系。行为结果表明 RTs 中存在 DRB 效应，该效应受初始响应和探针刺激开始之间的响应刺激间隔 (RSI) 持续时间的影响。实际上，在 500 毫秒的短 RSI 中观察到 DRB 效应，但在 2000 毫秒的较长 RSI 中没有观察到 DRB 效应，表明事件文件随时间分解。EEG 结果显示 RSI-2000 条件下的个体 DRB 与初始和探测响应后的运动后 beta 同步之间存在正相关。波束成形器分析将这种相关效应定位于枕中回，其与中央前区和顶叶下脑区的一致性也最高。总之，这些发现表明运动后 beta 同步是事件文件解体的标志，左中枕回是视觉 DRB 任务中刺激-反应结合的枢纽区域。
