摘要

过度的网络游戏已经成为一个日益严重的公共健康问题，与认知功能（特别是抑制控制缺陷和冲动增加）和相关大脑区域（如背外侧前额叶皮层，DLPFC）的变化密切相关。作为一种非侵入性脑刺激技术，经颅直流电刺激（tDCS）可能通过调节DLPFC的活动来改善这些认知缺陷，但其在过度网络游戏人群中的具体作用和机制仍有待进一步阐明。本研究旨在探讨经颅直流电刺激（tDCS）对右背外侧前额叶皮层（rDLPFC）过度网络游戏使用行为的调节作用。将57名网络游戏过度使用者随机分为真实tDCS刺激组（1.5mA，20分钟）和假tDCS刺激组。我们评估了他们在刺激前后对网络游戏相关干扰物的冲动程度和抑制控制。比较刺激前和刺激后的真实tDCS和假手术组，抑制控制（GO/NOGO任务）和冲动性（BIS-11）的测量结果显示假手术组没有显著变化。然而，真正的tDCS显著增强了抑制控制（提高了总体准确性，降低了NOGO错误率，延长了GO反应时间），并显著降低了冲动性（降低了BIS-11总分和分量表得分）。这些结果表明，tDCS刺激rDLPFC可以增强抑制控制能力，降低冲动性，对过度网络游戏者有积极影响。

The effect of a single session of transcranial direct current stimulation on inhibitory control and impulsivity in users with excessive Internet gaming: A double-blind, randomized controlled trial

Excessive Internet gaming has become an increasingly serious public health problem, closely related to changes in cognitive function (especially inhibitory control deficits and increased impulsivity) and related brain regions (such as the dorsolateral prefrontal cortex, DLPFC). As a non-invasive brain stimulation technique, transcranial direct current stimulation (tDCS) may improve these cognitive deficits by regulating the activity of DLPFC, but its specific effects and mechanisms in the excessive Internet gaming population still need to be further clarified. This study aims to investigate the regulatory effect of transcranial direct current stimulation (tDCS) on the right dorsolateral prefrontal cortex (rDLPFC) on excessive Internet game usage behavior. Fifty-seven excessive Internet game users were randomly divided into real tDCS stimulation (1.5 mA,20 min) and sham tDCS stimulation. We assessed their degree of impulsivity and inhibitory control of Internet gaming-related distractors before and after stimulation.Comparing pre- and post-stimulation with real versus sham tDCS, measures of inhibitory control (GO/NOGO task) and impulsivity (BIS-11) revealed no significant changes in the sham group. However, real tDCS significantly enhanced inhibitory control (increased total accuracy, decreased NOGO error rate, and prolonged GO reaction time) and significantly reduced impulsivity (decreased BIS-11 total and subscale scores).These results indicate that tDCS stimulating rDLPFC can enhance inhibitory control ability and reduce impulsivity, having a positive impact on excessive Internet gamers.

期刊介绍： Behavioural Brain Research is an international, interdisciplinary journal dedicated to the publication of articles in the field of behavioural neuroscience, broadly defined. Contributions from the entire range of disciplines that comprise the neurosciences, behavioural sciences or cognitive sciences are appropriate, as long as the goal is to delineate the neural mechanisms underlying behaviour. Thus, studies may range from neurophysiological, neuroanatomical, neurochemical or neuropharmacological analysis of brain-behaviour relations, including the use of molecular genetic or behavioural genetic approaches, to studies that involve the use of brain imaging techniques, to neuroethological studies. Reports of original research, of major methodological advances, or of novel conceptual approaches are all encouraged. The journal will also consider critical reviews on selected topics.
