Abstract

The core network refers to a set of neural regions that have been consistently associated with episodic memory retrieval and episodic future simulation. This network is thought to support the constructive thought processes that allow the retrieval and flexible combination of stored information to reconstruct past and construct novel future experiences. Recent behavioral research points to an overlap between these constructive processes and those also engaged during divergent thinking-the ability to think creatively and generate novel ideas-but the extent to which they involve common neural correlates remains unclear. Using fMRI, we sought to address this question by assessing brain activity as participants recalled past experiences, simulated future experiences, or engaged in divergent thinking. Consistent with past work, we found that episodic retrieval and future simulation activated the core network compared with a semantic control condition. Critically, a triple conjunction of episodic retrieval, future simulation, and divergent thinking revealed common engagement of core network regions, including the bilateral hippocampus and parahippocampal gyrus, as well as other regions involved in memory retrieval (inferior frontal gyrus) and mental imagery (middle occipital gyrus). The results provide further insight into the roles of the hippocampus and the core network in episodic memory retrieval, future simulation, and divergent thinking and extend recent work highlighting the involvement of constructive episodic processes in creative cognition.

  • A core network of brain regions including medial temporal, medial prefrontal, midline, and parietal regions is engaged both when participants recall the past and when they imagine possible futures, suggesting a common neural substrate.

    “A “core network” of brain regions including medial temporal, medial prefrontal, midline, and parietal regions is engaged both when participants recall the past and when they imagine possible futures, suggesting that these processes rely on a common neural substrate [3, 4, 8, 9].”

    From Constructive episodic simulation in dreams (2022) · cites this paper as [4]

  • The medial temporal, medial prefrontal, midline and parietal brain regions make up a core network engaged during episodic recall and imagining the future.

    “For instance, the medial temporal, medial prefrontal, midline and parietal brain regions make up a ‘core network’ that is engaged during episodic recall and imagining the future [25–27,33–36]”

    From Is episodic-like memory <i>like</i> episodic memory? (2024) · cites this paper as [26]

  • Both remembering the past and imagining the future depend on a common neural substrate.

    “suggesting that both processes depend on a common neural substrate [17,25–27].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
