Abstract

To remember the prospective intention successfully, going back and forth between the background task and the intention, i.e., the dynamics of these multiple processes can be critical. An executive function like task switching has been associated with the success of prospective memory (PM) in children, but the neural mechanism of PM in children has not been investigated. The purpose of this study was to reveal the dynamic functional connectivity underlying the success of PM in children. Healthy 108 children, aged 7 to 15, were engaged in a single trial PM task, with a 30-min delay. Temporal variabilities in their resting-state functional connectivity were analyzed, using sliding windows with seed regions of interest ROIs of the PM network. About 70% of children successfully remembered the intention; they showed greater dynamics in neural connectivity between the right dorsolateral prefrontal cortex (DLPFC) and intraparietal sulcus, and between the right DLPFC and insula as compared to children with PM failure. Everyday activities and the usual attention to ongoing processes can be associated with alertness in the right frontoparietal network and internal-state monitoring in the insula network, and those dynamics might be associated with one-time event PM success in children.

动态功能连接与儿童前瞻记忆成功相关
为了成功地记住预期意图,在背景任务和意图之间来回切换,也就是说,这些多个过程的动态变化是至关重要的。任务转换等执行功能与儿童前瞻记忆(PM)的成功有关,但其神经机制尚未被研究。本研究的目的是揭示儿童PM成功的动态功能连接。108名7 ~ 15岁的健康儿童参与了一项单次延迟30分钟的PM任务。利用带感兴趣roi种子区域的滑动窗口分析了PM网络静息状态功能连通性的时间变化。约70%的儿童成功地记住了意图;他们在右背外侧前额叶皮层(DLPFC)和顶叶内沟之间,以及右DLPFC和脑岛之间的神经连通性表现出比PM失败的儿童更大的动态。日常活动和对正在进行的过程的通常关注可能与右侧额顶叶网络的警惕性和脑岛网络的内部状态监测有关,这些动态可能与儿童一次性事件PM成功有关。
