摘　　要：偏侧化预备电位(Lateralized readiness potential,LRP)是与运动准备相关的一个脑电成分,基于运动肢体对侧大脑皮层的预备电位波幅高于同侧的特点而获得。LRP作为反应准备的在线测量方法,获得并准确检测其出现是关键,而了解其特点及影响因素是恰当运用该方法的保证。未来研究应着力于提高LRP的效度,将LRP与其它测量方法相结合。Lateralized readiness potential （ LRP） refers to negative lateralized readiness potential which occurs to the cerebral cortex contra-lateral to the response effectors .The crux of LRP analysis is to find the appropriate ＆quot;onset＆quot;time and the guar-antee of using LRP in appropriate way is to understand its character and affect factors .Limitations of the current literature are also addressed , and future areas of inquiry are suggested .
