Alter spontaneous activity in amygdala and vmPFC during fear consolidation following 24 h sleep deprivation

Abstract

Sleep deprivation (SD) has been associated with cognitive and emotional disruptions, however its impact on the acquisition of fear and subsequent fear memory consolidation remain unknown. To address this question, we measured human brain activity before and after fear acquisition under conditions of 24 h sleep deprivation versus normal sleep using resting-state functional magnetic resonance imaging (rs-fMRI). Additionally, we explored whether the fear acquisition-induced change of brain activity during the fear memory consolidation window can be predicted by subjective fear ratings and autonomic fear response, assessed by skin conductance responses (SCR) during acquisition. Behaviorally, the SD group demonstrated increased subjective and autonomic fear responses compared to controls at the stage of fear acquisition. During the stage of fear consolidation, the SD group displayed decreased ventromedial prefrontal cortex (vmPFC) activity and concomitantly increased amygdala activity. Moreover, in the SD group fear acquisition-induced brain activity changes in amygdala were positively correlated with both, subjective and autonomic fear indices during acquisition, whereas in controls changes vmPFC activity were positively correlated with fear indices during acquisition. Together, the present findings suggested that SD may weaken the top-down ability of the vmPFC to regulate amygdala activity during fear memory consolidation. Moreover, subjective and objective fear at fear acquisition stage can predict the change of brain activity in amygdala in fear memory consolidation following SD.

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Sleep deprivation is associated with lower vmPFC-amygdala functional connectivity.

    “Prior research links vmPFC-amygdala functional connectivity with sleep, suggesting that sleep deprivation (a common condition reported by students during the college years) is associated with lower vmPFC-amygdala functional connectivity [24, 105].”
  • Previous studies find that sleep deprivation is related to weaker vmPFC-amygdala RSFC.

    “In terms of sleep, previous studies [24, 105] find that sleep deprivation is related to weaker vmPFC-amygdala RSFC.”

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.
