This study investigated the effects of mental effort exerted during video-game play on features of the EEG in juvenile subjects diagnosed with seizure disorders and in age-matched clinically healthy subjects.
EEG was recorded from 14 children (9-15 years old) as they played a video game, watched another person playing a video-game, and sat quietly with their eyes open. Seven of the subjects had been clinically diagnosed with seizure disorders, three of whom had also exhibited photosensitivity.
Three spectral components of the EEG showed cognitive load-related modulation. The amplitude of a frontal midline theta (6-7 Hz) signal increased with video-game play relative to the watching and eyes open resting conditions. A posterior alpha band (9-12 Hz) signal was attenuated during the playing and the watching conditions relative to the resting condition. A central mu (10-13 Hz) rhythm was attenuated during the game-playing condition. No significant differences were found between the patient and control groups for any of these features. Incidence of epileptiform events did not discriminate test conditions in the children with epilepsy.
The results from this small sample suggest that video-game play tends to produce similar responses from children with epilepsy and in healthy control subjects. These responses in the juvenile population are similar to responses elicited by increased mental load in normal adult populations.
本研究调查了电子游戏过程中所付出的脑力劳动对被诊断患有癫痫症的青少年受试者以及年龄匹配的临床健康受试者脑电图特征的影响。
记录了14名儿童（9至15岁）在玩电子游戏、观看他人玩电子游戏以及睁眼安静坐着时的脑电图。其中7名受试者临床诊断患有癫痫症，其中3名还表现出光敏性。
脑电图的三个频谱成分显示出与认知负荷相关的调制。相对于观看和睁眼静息状态，额中线θ波（6至7赫兹）信号的幅度在玩电子游戏时增加。相对于静息状态，后α波段（9至12赫兹）信号在玩游戏和观看状态下减弱。中央μ波（10至13赫兹）节律在玩游戏状态下减弱。在这些特征方面，患者组和对照组之间未发现显著差异。癫痫样事件的发生率在癫痫儿童中未区分测试条件。
这个小样本的结果表明，玩电子游戏往往会使癫痫儿童和健康对照受试者产生相似的反应。青少年人群中的这些反应与正常成年人群中因精神负荷增加而引发的反应相似。
