Abstract

Self-generated cognitions, such as recalling personal memories or empathizing with others, are ubiquitous and essential for our lives. Such internal mental processing is ascribed to the Default Mode Network, a large network of the human brain, though the underlying neural and cognitive mechanisms remain poorly understood. Here, we tested the hypothesis that our mental experience is mediated by a combination of activities of multiple cognitive processes. Our study included four functional MRI experiments with the same participants and a wide range of cognitive tasks, as well as an analytical approach that afforded the identification of cognitive processes during self-generated cognition. We showed that several cognitive processes functioned simultaneously during self-generated mental activity. The processes had specific and localized neural representations, suggesting that they support different aspects of internal processing. Overall, we demonstrate that internally directed experience may be achieved by pooling over multiple cognitive processes.

  • A set of brain regions in the frontal, parietal, and medial temporal lobes consistently become active when people let their minds wander and engage in self-reflection.

    “It turns out that a set of brain regions in the frontal, parietal, and medial temporal lobes consistently become active when people let their minds wander and engage in self-reflection, mentally traveling back and forth through time to learn from the past and plan for the future (Axelrod et al., 2017).”

    From Self and identity in personality psychology (2021) · cites this paper as Axelrod et al., 2017

    The Introduction (page unavailable) links the default mode network to mind wandering, self-referential thought, and thinking about the past and future. The Results (Experiment 2) and Discussion identify frontal and parietal regions involved in self-referential processing and a parahippocampal region involved in scene construction. But the study examined task-initiated thought, not mind wandering directly, and it does not show that all the named regions consistently become active together during mind wandering and self-reflection.

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.
