Visual perspective, recalling events from one's own eyes or one of several possible observer viewpoints, is a fundamental aspect of AM. Yet, exactly how visual perspective influences the functional mechanisms supporting retrieval is unclear. Here we used a multivariate analysis to characterize the spatiotemporal dynamics of networks supporting AM retrieval from multiple typical and atypical visual perspectives. Both own eyes and observer perspectives engaged an AM retrieval network (i.e., hippocampus, anterior and posterior midline, and lateral frontal and posterior cortices) that peaked during later retrieval periods, but was recruited less strongly for observer perspectives. Functional connectivity analyses with an anterior hippocampal seed revealed that visual perspective also affected the strength and timing of neural recruitment. There was stronger hippocampal connectivity with a posterior medial network during the initial retrieval of AMs from atypical observer perspectives and stronger within-MTL and ventromedial prefrontal cortex connectivity during later retrieval periods from own eyes perspectives, suggesting that visual perspective is an important factor in understanding how neocortical systems guide memory retrieval. Our findings demonstrate that adopting own eyes and observer perspectives during AM retrieval is correlated with distinct patterns of hippocampal–neocortical interactions associated with differential recruitment of the AM retrieval network during later retrieval periods, thereby supporting the central role of visual perspective in reconstructing the personal past.

视觉透视图可以从自己的眼睛或几种可能的观察者视角之一回忆事件，这是AM的基本方面。然而，不清楚视觉视角如何影响支持检索的功能机制。在这里，我们使用了多元分析来从多个典型和非典型的视觉角度描述支持AM检索的网络的时空动态。自己的眼睛和观察者的视角都参与了AM检索网络（即海马，前中线和后中线以及外侧额叶和后皮层），该网络在以后的检索期间达到顶峰，但对于观察者的观点而言，招募的力度较小。用海马前种子进行功能连接分析表明，视觉角度也影响神经募集的强度和时间。从非典型观察者的角度对AM进行初始取回期间，与后内侧网络的海马连接增强，而在从自身的眼睛角度取回的后期，在MTL内部和腹侧前额叶皮层的连通性较强，这表明视觉角度是了解如何新皮层系统指导记忆检索。我们的研究结果表明，在AM检索过程中采用自己的眼睛和观察者的视角与海马-神经交互作用的不同模式相关，后者与AM检索网络在后期检索期间的差异招募相关，从而支持了视觉视角在重建个人过去时的核心作用。
