运动准备过程中的神经机制相关研究进展

The progress of preparation for action in event-related potential (ERP) study

日常生活中,人们持续修正行为来确保他们能够适应环境,在体育运动中更是如此。"perception–action cycle"概念,强调对结果的知觉与执行网络之间持续的相互影响。在准备阶段中存在两个事件相关电位(ERP)成分:单侧预备电位(LRP)以及关联负波(CNV),这两个成分的出现代表不同的准备过程。在运动准备过程中,刺激-反应相关的先验概率(prior probability,PP)在决策制定过程和行为表现调节中起重要作用。LRP和CNV是研究先前信息对准备过程影响的重要指标。CNV与人的注意力以及大脑皮层的兴奋集中能力密切相关,是与预期注意、准备、运动和信息加工相关的皮质激活。

People continued corrective action to ensure that they can adapt to the environment, especially in sport. Fuster proposed ＂perception-action cycle＂ concept in 2004, emphasized the continuing impact between the result perceptions and the implementation of the network. There are two event-related potential （ERP） components in the preparation phase： LRP and contingent negative variation（CNV）, they represent a different preparation process. In the process of preparing, prior probability（PP） plays an important role. LRP and CN~ are important indicators of the impact of the previous research to the process of preparing. CNV excites with human ability to focus attention, and is closely related to the cerebral cortex, and CNV is cortical activation about attention, preparation and information processing.
