| 摘 要： | 目的: 本研究分析睡眠剥夺对个体选择性注意网络冲突效应和脑电样本熵的影响,探讨睡眠剥夺对大脑注意网络的影响。方法: 25名健康受试者参与36 h完全睡眠剥夺试验。试验于当天9:00开始,于次日21:00结束,试验采用自身前后对照设计。受试者在睡眠剥夺前后分别完成注意网络任务,同步采集受试者的脑电图。用脑电样本熵算法分析脑电图的delta、theta、alpha、beta和gamma频率段的脑电复杂度并对比各频段脑电样本熵在睡眠剥夺前、后的变化。结果: 同睡眠剥夺前比较,睡眠剥夺后与受试者的注意网络冲突效应密切相关的反应时显著下降(P＜0.01),正确率显著增加(P＜0.01)。脑电样本熵分析发现在beta频率段,与注意网络冲突控制相关的脑电样本熵值在睡眠剥夺后明显增大(P＜0.01)。其余脑电频率段脑电样本熵未发现显著差异。结论: 表明完全睡眠剥夺后大脑的注意网络冲突效应降低,表明睡眠剥夺后执行冲突控制能力的下降。

| Abstract: | Objective: To explore the effects of total sleep deprivation (TSD) on brain attention network and to analyze the effects of sleep deprivation on individual selective attention network conflict effect and electroencephalograph (EEG) sample entropy. Methods: Twenty-five healthy subjects participated in the test from 9: 00am that day to 9: 00pm next day. The subjects completed the attention network task (ANT) before and after TSD, and synchronously recorded the EEG signals. Sample entropy algorithm was used to analyze the changes of EEG complexity in delta, theta, alpha, beta and gamma frequency bands before and after TSD. Results: Compared with before TSD, the reaction time of attention network conflict effect was significantly decreased after TSD (P＜0. 01), and rate was increased significantly (P＜0. 01). Sample entropy analysis of EEG showed that in beta frequency bands, the sample entropy related to attention network conflict control was increased significantly after TSD (P＜0. 01). No significant difference was found in other EEG frequency bands. Conclusion: TSD reduces the effect of brain attention network conflict, reflecting the decline of conflict control ability after 36 h TSD. |
