运动想象训练被认为是运动技能学习和运动功能康复的有效训练策略。然而，与运动想象的神经机制研究相比，运动想象训练的神经影像学研究相对较少。采用功能磁共振成像技术，设计了一个为期2周的运动表象训练实验，包括执行任务和表象任务，旨在探讨运动表象训练对提高运动成绩的有效性，以及运动表象训练的神经机制。在这里，我们研究了运动行为，大脑激活，以及运动执行任务的行为和大脑激活之间的相关性在任务相关的兴趣区（ROI）在前和后测试阶段。我们的研究结果表明，运动想象训练可以提高运动成绩。更重要的是，在两种任务的梭状回中发现了训练引起的脑功能改变。这些发现为运动想象训练提供了新的见解。
Motor imagery training is considered as an effective training strategy for motor skill learning and motor function rehabilitation. However, compared with studies of the neural mechanism underlying motor imagery, neuroimaging examinations of motor imagery training are comparatively few. Using functional magnetic resonance imaging, we designed a 2-week motor imagery training experiment, including execution and imagery tasks, to investigate the effectiveness of motor imagery training on the improvement of motor performance, as well as the neural mechanism associated with motor imagery training. Here, we examined the motor behavior, brain activation, and correlation between the behavior of the motor execution task and the brain activation across task-related region of interests (ROIs) in both pre- and post-test phases. Our results demonstrated that motor imagery training could improve motor performance. More importantly, the brain functional alterations induced by training were found in the fusiform gyrus for both tasks. These findings provide new insights into motor imagery training.
