Executive functions are higdevel cognitive processes that make possible the formation of flexible and adaptive goal-directed behaviors and the frontal lobes regulate these functions. The purpose of this study was to investigate the relationship between frontal EEG coherence in theta, alpha, and beta bands and executive functions in adults. A sample of 168 students ( = 25.44 years, = 4.52) were included in this study. EEG records were recorded at the psychology laboratory of Mohaghegh Ardabili University (Iran), then intrahemispheric and interhemispheric coherence of frontal regions were analyzed using the NeuroGuide software. The participants were asked to fill in the Adult Executive Skills Questionnaire. Correlational results showed that there is a positive relationship between executive functions and EEG coherence in theta, alpha, and beta bands in frontal regions of the left hemisphere, EEG coherence of alpha and beta bands in frontal regions of the right hemisphere and EEG coherence of alpha band between frontal regions of the two hemispheres. The results of the regression analysis also revealed that coherence of alpha, beta, and theta bands between left and right frontal regions and coherence of beta and theta bands in the left frontal regions predict executive functions. These results indicate that the common activity of frontal cortex, especially the left hemisphere, is associated with executive functions and cognitive control.
执行功能是高级认知过程，使形成灵活和适应性的目标导向行为成为可能，而额叶调节这些功能。本研究的目的是调查成人额 EEG 同步在 theta、alpha 和 beta 波段与执行功能之间的关系。本研究纳入了 168 名学生（ = 25.44 岁， = 4.52）。EEG 记录在伊朗莫哈加赫阿迪卜大学的心理学实验室进行记录，然后使用 NeuroGuide 软件分析额区的半球内和半球间同步性。参与者被要求填写成人执行技能问卷。相关结果表明，左额区 theta、alpha 和 beta 波段的执行功能与 EEG 同步性呈正相关，右额区 alpha 和 beta 波段的 EEG 同步性与两个半球额区之间的 alpha 波段的 EEG 同步性呈正相关。回归分析的结果还表明，左右额区之间的 alpha、beta 和 theta 波段的同步性以及左额区的 beta 和 theta 波段的同步性可以预测执行功能。这些结果表明，额叶皮层的共同活动，特别是左半球，与执行功能和认知控制有关。
