Abstract

Recent research on changing fears has examined targeting reconsolidation. During reconsolidation, stored information is rendered labile after being retrieved. Pharmacological manipulations at this stage result in an inability to retrieve the memories at later times, suggesting that they are erased or persistently inhibited. Unfortunately, the use of these pharmacological manipulations in humans can be problematic. Here we introduce a non-invasive technique to target the reconsolidation of fear memories in humans. We provide evidence that old fear memories can be updated with non-fearful information provided during the reconsolidation window. As a consequence, fear responses are no longer expressed, an effect that lasted at least a year and was selective only to reactivated memories without affecting others. These findings demonstrate the adaptive role of reconsolidation as a window of opportunity to rewrite emotional memories, and suggest a non-invasive technique that can be used safely in humans to prevent the return of fear.

  • Reactivation during wakefulness destabilized memories rendering them susceptible to interference learning, as indicated by impaired memory recall for the originally learned card-pair locations after interference learning.

    “As expected from reconsolidation studies (e.g., Refs.844, 845, 1043), reactivation during wakefulness destabilized memories rendering them susceptible to interference learning, as indicated by impaired memory recall for the originally learned card-pair locations after interference learning (FIGURE 4D).”

    From About Sleep's Role in Memory (2013) · cites this paper as [1043]

    The Persistence of reconsolidation blockade section (page not provided) says reactivation rendered fear memories labile and extinction during that period prevented the return of fear. The paper does not report a card-pair location task or impaired recall of originally learned locations after interference learning; its experiments measured conditioned fear responses.

  • The first studies that translated findings in non-human animals to humans used classical aversive conditioning to induce a simple emotional memory.

    “The first studies that translated findings in non-human animals [48,88,89] to humans used classical aversive conditioning to induce a simple emotional memory [94,95].”
  • Conditioned physiological responses could be eliminated by presenting a single reminder cue and administering propranolol or an extinction procedure within the putative reconsolidation window.

    “These showed that conditioned physiological responses could be eliminated by presenting a single reminder cue (the CS+) and administering a pharmacological agent (the beta-adrenergic antagonist propranolol [95]) or a behavioural intervention (an extinction procedure [94]) within the putative reconsolidation window.”
  • The effect of retrieval + extinction on attenuation of spontaneous recovery and reinstatement was evident a year after the original acquisition of fear.

    “Following this work, Schiller et al. (59), using skin conductance measures, showed that retrieval + extinction (with 10 min but not 6 h between sessions) attenuated spontaneous recovery and reinstatement of fear in human subjects, an effect that was evident a year after the original acquisition of fear.”

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.
