Abstract

Background

Methamphetamine (MA) dependence is associated with elevated rates cognitive impairment in MA users. The objective of the present study was to investigate the effects of virtual reality (VR) competitive cycling excise on the neurocognitive functions and on negative affectivity of MA-dependent individuals.

Methods

Thirty MA-dependent individuals performed a colour-word Stroop task and underwent a profile of mood states (POMS) scale assessment both before and after a 10 min VR competitive cycling exercise. Functional near-infrared spectroscopy (fNIRS) were recorded during the pre-and post-exercise Stroop tasks and during rest.

Results

After acute exercise, neural activity, along with improved Stroop performance, was enhanced significantly in the dorsolateral prefrontal cortex. Also observed during post-exercise Stroop tasks was a more efficient network architecture in the topological organization of brain networks than during the pre-exercise Stroop tasks. As for resting states before versus after exercisethe, we detected an increased functional connectivity between the prefrontal cortex and the motor cortex after exercise.

Conclusions

These results suggest that an acute bout of VR competitive cycling exercise facilitates executive information processing by enhancing task-related cortical activations and brain functional network efficiency in MA-dependent individuals.

急性VR竞技自行车运动可增强ma依赖个体的皮质激活和脑功能网络效率

背景:甲基苯丙胺(MA)依赖与MA使用者认知障碍发生率升高有关。本研究的目的是探讨虚拟现实(VR)竞技自行车运动对ma依赖个体神经认知功能和消极情绪的影响。方法:30名ma依赖者在进行10分钟VR竞技自行车运动前后分别进行了色词Stroop任务和情绪状态量表评估。记录运动前、运动后Stroop任务和休息时的功能近红外光谱(fNIRS)。结果急性运动后，大鼠背外侧前额叶皮质区神经活动显著增强，Stroop表现改善。同时观察到，在训练后的Stroop任务中，大脑网络拓扑组织的网络结构比训练前的Stroop任务更有效。至于运动前和运动后的静息状态，我们发现运动后前额叶皮层和运动皮层之间的功能连接有所增加。结论急性VR竞技自行车运动通过增强ma依赖个体的任务相关皮层激活和脑功能网络效率，促进执行信息加工。

期刊介绍： Neuroscience Letters is devoted to the rapid publication of short, high-quality papers of interest to the broad community of neuroscientists. Only papers which will make a significant addition to the literature in the field will be published. Papers in all areas of neuroscience - molecular, cellular, developmental, systems, behavioral and cognitive, as well as computational - will be considered for publication. Submission of laboratory investigations that shed light on disease mechanisms is encouraged. Special Issues, edited by Guest Editors to cover new and rapidly-moving areas, will include invited mini-reviews. Occasional mini-reviews in especially timely areas will be considered for publication, without invitation, outside of Special Issues; these un-solicited mini-reviews can be submitted without invitation but must be of very high quality. Clinical studies will also be published if they provide new information about organization or actions of the nervous system, or provide new insights into the neurobiology of disease. NSL does not publish case reports.
