Abstract：
In this study, event-related potentials and neurobehavioral measurements were used to investigate the effects of discontinuous short-term fine motor imagery (MI), a paradigm of finger sequential MI training interspersed with no-MI that occurs within 1 hr, on fine finger motor execution. The event-related potentials revealed that there were significant differences in the P300 between the fine MI training and the no-MI training. There were also significant changes in the P200 between fine motor execution of familiar tasks after MI training and fine motor execution of unfamiliar tasks without MI training. Neurobehavioral data revealed that the fine MI enhanced fine motor execution. These findings may suggest that discontinuous short-term fine MI could be useful in improving fine motor skills.
摘要：
在这项研究中,事件相关电位和神经行为测量用于研究不连续短期精细运动想象（MI）的影响，手指顺序MI训练的范例散布在1小时内发生的无MI，精细手指电机执行。事件相关电位显示，精细MI训练和无MI训练之间的P300存在显着差异。在MI训练后熟悉任务的精细运动执行与在没有MI训练的情况下不熟悉任务的精细运动执行之间，P200也发生了显着变化。神经行为数据显示，精细MI增强了精细运动执行。这些发现可能表明，不连续的短期精细MI可能有助于提高精细运动技能。
