项目摘要

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.

本研究的目的是探讨人类运动想象的神经生理机制，并解决运动想象的神经学背景，因为它是一个普遍的共识，他们是两个勤奋的运动学习类型：获得运动技能（获得新的运动板条的运动学习）和刷上运动滑雪（获得的技能的运动学习;运动技能的训练）。虽然如上所述，运动学习的类型定义是明确的，但也有一些下流的：，它是不为人所知的神经生理机制有关的运动学习这是一个严重的问题，不开发有效的运动训练方法的神经科学的运动和神经康复领域。因此，本研究进行了调查的神经生理机制的“运动想象”，这反映了人类的认知功能。具体地说，我们记录了运动诱发电位（MEP）引起的第一背间肌在三种条件下，在休息，在运动想象和自愿收缩，分别。根据这些结果，我们证实了运动想象的神经通路与随意收缩的神经通路是一致的。此外，与运动想象相关的神经通路对指令敏感，因此可以通过运动观察来改变。综上所述，我们首次阐明了磁刺激法产生“运动想象”的神经机制。
