对时间间隔的附带编码持续时间的估计（回顾性持续时间处理）被认为依赖于与事件序列相关联的上下文信息的检索，其自动编码在内侧颞叶区域中。“时间细胞”已经在海马体（HC）中被描述，编码事件的时间进展及其持续时间。然而，HC是否支持人类明确的回顾性持续时间判断，以及涉及哪些神经动力学，仍然知之甚少。在这里，我们使用静息态功能磁共振成像测试的HC的内在连接模式的变化之间的关系，并在回顾性持续时间处理的个体差异，评估使用一种新的任务，涉及生态刺激的介绍。结果表明，回顾性的持续时间歧视性能预测的变化，在固有的连接的双边HC与右中央前回;后续的探索性分析表明的作用，CA 1和CA 4/DG子字段在驱动所观察到的模式。研究结果提供了与第二范围内的持续时间的内隐处理相关的神经网络的见解。
The estimation of incidentally encoded durations of time intervals (retrospective duration processing) is thought to rely on the retrieval of contextual information associated with a sequence of events, automatically encoded in medial temporal lobe regions. “Time cells” have been described in the hippocampus (HC), encoding the temporal progression of events and their duration. However, whether the HC supports explicit retrospective duration judgments in humans, and which neural dynamics are involved, is still poorly understood. Here we used resting-state fMRI to test the relation between variations in intrinsic connectivity patterns of the HC, and individual differences in retrospective duration processing, assessed using a novel task involving the presentation of ecological stimuli. Results showed that retrospective duration discrimination performance predicted variations in the intrinsic connectivity of the bilateral HC with the right precentral gyrus; follow-up exploratory analyses suggested a role of the CA1 and CA4/DG subfields in driving the observed pattern. Findings provide insights on neural networks associated with implicit processing of durations in the second range.
