Abstract

Despite extensive research into executive function (EF), the precise relationship between brain dynamics and flexible cognition remains unknown. Using a large, publicly available dataset (189 participants), we find that functional connections measured throughout 56min of resting state fMRI data comprise five distinct connectivity states. Elevated EF performance as measured outside of the scanner was associated with greater episodes of more frequently occurring connectivity states, and fewer episodes of less frequently occurring connectivity states. Frequently occurring states displayed metastable properties, where cognitive flexibility may be facilitated by attenuated correlations and greater functional connection variability. Less frequently occurring states displayed properties consistent with low arousal and low vigilance. These findings suggest that elevated EF performance may be associated with the propensity to occupy more frequently occurring brain configurations that enable cognitive flexibility, while avoiding less frequently occurring brain configurations related to low arousal/vigilance states. The current findings offer a novel framework for identifying neural processes related to individual differences in executive function.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • People with higher Wisconsin Card Sorting Test scores show more episodes of frequently occurring brain states and fewer episodes of infrequent states previously linked to low vigilance and arousal.

    “Individuals who score higher on the WCST exhibit more episodes of more frequently occurring brain states, and fewer episodes of less frequently occurring brain states that have previously been associated with low vigilance and arousal44 (Fig. 2c).”
  • Some whole-brain dynamic patterns are linked to higher cognitive flexibility.

    “it has been shown that certain patterns of whole-brain dynamics are associated with elevated levels of cognitive flexibility.”
  • Individuals who score higher on a card sort task exhibit whole-brain functional connectivity dynamics characterized by greater episodes of more frequently occurring brain states and fewer episodes of less frequently occurring states associated with low vigilance and arousal.

    “Individuals who score higher on a card sort task exhibited whole-brain functional connectivity dynamics characterized by greater episodes of more frequently occurring brain states, and fewer episodes of less frequently occurring states associated with low vigilance and arousal (107).”

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.
