Changes of the brain network with motor learning

通过反复训练，我们能够更快更准确地完成预定的动作。在这个过程中，大脑活动发生了变化。本研究的目的是探讨TMS-EEG技术是否可以检测到运动学习时大脑网络的变化，特别是初级运动皮层与其他大脑区域之间的关系。在连续一周的手指敲击训练后，诱发电位的峰值和潜伏期在不同的训练中没有变化。实验结果表明，在某些领域，表现与阶段同步程度之间存在显著的相关性，这些领域随着技能习得的不同而发生变化。

With repeated training, we are able to do quicker and more accurately an intended movement. The brain activity is changed in the process. The purpose of this study was to investigate whether the TMS-EEG technique can detect an alternation of the brain network with motor learning, especially in the relationship between the primary motor cortex and other brain regions.After a week of sequential finger tapping training, the peak of evoked potentials and those latencies did not change among the sessions. A significant correlation between the performance and the degree of phase synchronization in trials was found in some areas, and those areas were changed depending on skill acquisition.
