【摘要】：目的:基于大脑局部一致性(Re Ho)方法探测小球类运动员静息状态下脑功能活动的可塑性变化。方法:收集小球类学生运动员和与之匹配的对照人群,采集静息态功能磁共振数据,计算大脑局部一致性Re Ho指标。结果:运动员组在左侧前扣带回、脑岛、丘脑和小脑蚓部的ReHo值高于对照组,这些脑区是负责心脏——血管调节和反馈的自主神经反应环路脑网络的重要节点。结论:运动员左侧前扣带回、脑岛、丘脑和小脑蚓部脑区存在更有效的自主神经反应环路,以在快节奏小球类运动中提高感知、集中、运动计划和快速反应。
[Abstract]:Objective: To investigate the plasticity of brain function activity in the resting state of small-ball-like athletes based on the method of brain partial coherence (Re Ho). Methods: A small ball type student and a control group matched with it were collected, and the rest state magnetic resonance data was collected and the local consistency Re Ho index of the brain was calculated. Results: The value of ReHo in the brain island, the thalamus and the vermis of the cerebellum was higher than that of the control group, and the brain regions were the important nodes of the brain network of the autonomic nerve reaction loop, which was responsible for the regulation and feedback of the cardiac _ blood vessels. Conclusion: There are more effective autonomic nerve reaction loops in the brain regions of the anterior cingulate gyrus, the brain island, the thalamus and the vermis of the cerebellum, so as to improve the perception, concentration, movement plan and rapid response in the fast-paced small ball-like movement.
