How movements are generated and controlled by the central nervous system (CNS) is still not well understood. In this work, we tested the hypothesis of a modular organization of the brain activity during the execution of voluntary movements. In particular, we extracted meta-stable topographies as a measure for global brain state, so-called microstates, from electroencephalography (EEG) data during pure planar reaching movements as well as reaching and grasping of different objects, and we compared them with those extracted during resting-state. The results showed the emergence of specific EEG microstates related to movement execution. Our results provide evidence about the benefits of EEG microstate analysis for motor control studies and their importance to better understand brain reorganization in neurological pathologies.
运动是如何由中枢神经系统（CNS）产生和控制的，目前仍未得到很好的理解。在这项研究中，我们测试了在执行自主运动过程中大脑活动模块化组织的假设。具体而言，我们从脑电图（EEG）数据中提取了元稳定地形图作为全局脑状态的一种度量，即所谓的微状态，这些数据来自于纯平面伸展运动以及对不同物体的伸展和抓握过程，并且我们将它们与静息状态下提取的微状态进行了比较。结果显示出与运动执行相关的特定EEG微状态的出现。我们的结果为EEG微状态分析在运动控制研究中的益处提供了证据，以及它们对于更好地理解神经病理学中大脑重组的重要性。
