Remembering to realize delayed intentions is a multi-phase process, labelled as prospective memory (PM), and involves a plurality of neural networks. The present study utilized the activation likelihood estimation method of meta-analysis to provide a complete overview of the brain regions that are consistently activated in each PM phase. We formulated the 'Attention to Delayed Intention' (AtoDI) model to explain the neural dissociation found between intention maintenance and retrieval phases. The dorsal frontoparietal network is involved mainly in the maintenance phase and seems to mediate the strategic monitoring processes, such as the allocation of top-down attention both towards external stimuli, to monitor for the occurrence of the PM cues, and to internal memory contents, to maintain the intention active in memory. The ventral frontoparietal network is recruited in the retrieval phase and might subserve the bottom-up attention captured externally by the PM cues and, internally, by the intention stored in memory. Together with other brain regions (i.e., insula and posterior cingulate cortex), the ventral frontoparietal network would support the spontaneous retrieval processes. The functional contribution of the anterior prefrontal cortex is discussed extensively for each PM phase.
记住实现延迟意图是一个多阶段的过程，被标记为前瞻性记忆（PM），并涉及多个神经网络。本研究利用元分析的激活可能性估计方法，提供了在每个 PM 阶段始终被激活的大脑区域的完整概述。我们提出了“延迟意图注意”（AtoDI）模型，以解释意图维持和检索阶段之间发现的神经分离。背侧额顶网络主要参与维持阶段，似乎介导了策略监测过程，例如自上而下地将注意力分配到外部刺激上，以监测 PM 线索的出现，以及内部记忆内容，以保持意图在记忆中活跃。腹侧额顶网络在检索阶段被招募，并可能支持由 PM 线索外部捕获的自下而上的注意力，以及在记忆中存储的意图内部的注意力。与其他大脑区域（即岛叶和后扣带皮层）一起，腹侧额顶网络将支持自发检索过程。前额叶皮层的功能贡献在每个 PM 阶段都有广泛的讨论。
