一个强有力的发现是，静息状态额叶θ/β比（TBR），一个自发的脑电图（EEG）频带参数，在注意力缺陷/多动障碍增加。越来越多的证据表明，TBR也可能为健康成人的执行认知控制（更具体地说，注意力控制; AC）提供客观标志。本研究的目的是进一步探讨这一概念，通过评估脑电图频带功率和AC两次（间隔一周）在41名年轻女性成年人。与我们的预测一致，TBR和特质AC之间的负相关，用经常使用的自我报告措施来衡量，被复制。结果还表明，重测信度的休息状态额叶TBR是非常好的（r=.93），而且，TBR测量在第一届预测AC在第二届（r=.44）。这些一致的结果进一步加强了额叶TBR可用作前额叶介导的执行AC的可靠生物标志物的概念。(C)© 2016 Elsevier B.

A robust finding is that resting-state frontal theta/beta ratio (TBR), a spontaneous electroencephalographic (EEG) frequency band parameter, is increased in attention-deficit/hyperactivity disorder. Accumulating evidence suggests that TBR might also provide an objective marker of executive cognitive control (and more specifically attentional control; AC) in healthy adults. The present study aimed to further investigate this conception by assessing EEG frequency band power and AC twice (with a one-week interval) in 41 young female adults. In line with our predictions, the negative association between TBR and trait AC, as measured with an often used self-report measure, was replicated. Results also demonstrated that test-retest reliability of resting-state frontal TBR was very good (r=.93) and, moreover, TBR measured at the first session predicted AC during the second session (r=.44). These consistent results further reinforce the notion that frontal TBR could be used as a reliable biomarker for prefrontally-mediated executive AC. (C) 2016 Elsevier B.V. All rights reserved.
