【摘要】：目的:基于大腦局部一致性(Re Ho)方法探測小球類運(yùn)動員靜息狀態(tài)下腦功能活動的可塑性變化。方法:收集小球類學(xué)生運(yùn)動員和與之匹配的對照人群,采集靜息態(tài)功能磁共振數(shù)據(jù),計(jì)算大腦局部一致性Re Ho指標(biāo)。結(jié)果:運(yùn)動員組在左側(cè)前扣帶回、腦島、丘腦和小腦蚓部的ReHo值高于對照組,這些腦區(qū)是負(fù)責(zé)心臟——血管調(diào)節(jié)和反饋的自主神經(jīng)反應(yīng)環(huán)路腦網(wǎng)絡(luò)的重要節(jié)點(diǎn)。結(jié)論:運(yùn)動員左側(cè)前扣帶回、腦島、丘腦和小腦蚓部腦區(qū)存在更有效的自主神經(jīng)反應(yīng)環(huán)路,以在快節(jié)奏小球類運(yùn)動中提高感知、集中、運(yùn)動計(jì)劃和快速反應(yīng)。
[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.
