Abstract

The results of an analysis of phase synchronization of theta brain activity in children when solving problems that involved computational abilities, visual search, and short-term operating memory have been presented. Functional connectivity within the temporal, frontal, central, and occipital-parietal areas of the cerebral cortex using EEG data has been calculated. Significant differences in the dynamics of synchronization of neuronal structures in the frequency range of the theta rhythm, both depending on the brain area and the type of performed task have been found. Significant increases in functional connectivity within prefrontal and temporal regions during visual search tasks have been found.

儿童解决认知任务时脑功能连通性的特征

在解决涉及计算能力、视觉搜索和短期操作记忆的问题时，儿童theta脑活动的相位同步分析结果已经被提出。利用脑电图数据计算了大脑皮层的颞、额、中央和枕顶叶区域的功能连通性。在theta节律的频率范围内，神经元结构同步的动态有显著差异，这取决于大脑区域和执行任务的类型。在视觉搜索任务中，前额叶和颞叶区域的功能连接显著增加。
