The purpose of the present study was to investigate neurphysiological mechanisms of human motor imagery and to address neurological background of motor imagery Because it is a general consensus that them are two diligent motor learning types; acquisition of motor skill (motor learning of acquisition of new motor slats) and brushing up motor ski (motor learning of acquired skills; training of motor skills). Although as mentioned above, definition of types of motor learning is clear, there are a few lewd:, and it is not well known about neurophysiological mechanisms related to motor learning This is a serious problem not to develop effective motor teaming methods for neurosciences of sports and neuro-rehabilitation areas.The present study, therefore, was undertaken to investigate neurophysiological mechanisms of 'motor imagery,' which reflects on human cognitive function. Concretely, we have recorded motor evoked potentials (MEPs) elicited from the first dorsal intersseous muscles under three conditions, at rest, during motor imagery and voluntary contraction, respectively. Based on the present results, we have confirmed that neural pathways of motor imagery are the same one of voluntary contraction. In addition, neural pathways related to motor imagery are sensitive to instruction and consequently are changeable by motor observation. In conclusion, for the first time we have clarified neural mechanisms of 'motor imagery' using magnetic stimulation method.

本研究的目的是研究人类运动图像的神经生理机制，并解决运动图像的神经系统背景，因为它们是两种勤奋的运动学习类型的一般共识。获取运动技能的获取（对新运动板的获取的运动学习）和刷摩托滑雪（手机学习的动态技能；培训运动技能）。尽管如上所述，运动类型的定义很明显，但有一些淫荡：与运动学习相关的神经生理机制尚不清楚，这是一个严重的问题，不开发有效的运动组合方法，用于运动和神经护理的神经科学方法。具体而言，我们记录了在三种条件下，在静止，运动图像和自愿收缩期间，在三种条件下从第一背侧肌肉肌肉中引起的运动电位（MEP）。根据目前的结果，我们已经确认运动图像的神经途径是自愿收缩的一种。此外，与运动图像有关的神经途径对指导很敏感，因此可以通过运动观察来改变。总之，我们首次使用磁刺激方法阐明了“运动图像”的神经机制。
