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.
运动想象训练被认为是一种有效的运动技能学习和运动功能康复训练策略。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。本研究采用功能磁共振成像技术，设计了一项为期 2 周的运动想象训练实验，包括执行任务和想象任务，以探讨运动想象训练对运动表现改善的有效性，以及与运动想象训练相关的神经机制。在这里，我们在前后测试阶段分别检查了运动执行任务的行为、任务相关感兴趣区域（ROIs）内的大脑激活以及大脑激活与行为之间的相关性。结果表明，运动想象训练可以提高运动表现。更重要的是，两种任务的梭状回都发现了训练引起的大脑功能改变。这些发现为运动想象训练提供了新的见解。
