【摘要】：想象动作(MI),或称运动想象,指大脑仅有动作意图但不实际执行,反映人对动作的期望及对将要发生真实动作的预演。MI与真实执行动作有相似的认知过程,由此可揭示运动行为心理过程与真实动作控制之间的关系。故MI成为探究动作执行时神经心理过程、检测大脑激活状态和研究大脑神经网络功能的重要工具。MI研究已历经数十年发展,检测手段和动作模式日益更新;MI诱发脑电同时含有认知心理和神经生理信息,已广泛用于人机交互,成为脑机接口控制的重要方法;MI还用于损伤脑区神经回路重建和帮助中风患者康复训练。MI生理信息检测及其应用具有重要科学意义和研究价值,本文主要回顾了相关研究方法(含MI过程检测手段、常用MI模式、MI在人机交互和康复中应用),简要讨论了所存在的问题并展望其未来发展,以期促进MI的深入研究与开发应用。
[Abstract]:Imaginary motion, or motion imagination, refers to the brain having only the intention to act but not the actual execution. Reflecting the expectation of action and the preview of real action, there is a similar cognitive process between real action and real action. This can reveal the relationship between the psychological process of motor behavior and the control of real action, so MI becomes the neuropsychological process of exploring the execution of action. The research of MI, an important tool to detect the activation state of brain and study the function of neural network, has been developed for tens of years. MI-induced EEG, which contains both cognitive psychological and neurophysiological information, has been widely used in man-machine interaction and has become an important method of brain-computer interface control. MI can also be used to reconstruct the neural circuit in injured brain area and to help stroke patients with rehabilitation training .MI physiological information detection and its application has important scientific significance and research value. This paper mainly reviews the relevant research methods (including MI process detection methods, commonly used MI mode and MI in human-computer interaction and rehabilitation applications), briefly discusses the existing problems and prospects for its future development. In order to promote the further research and development and application of MI.
