Fear Extinction as a Model for Translational Neuroscience: Ten Years of Progress

Open access
Milad, Mohammed R., Quirk, Gregory J.·2012·Annual Review of Psychology

Abstract

The psychology of extinction has been studied for decades. Approximately 10 years ago, however, there began a concerted effort to understand the neural circuits of extinction of fear conditioning, in both animals and humans. Progress during this period has been facilitated by a high degree of coordination between rodent and human researchers examining fear extinction. Here we review the major advances and highlight new approaches to understanding and exploiting fear extinction. Research in fear extinction could serve as a model for translational research in other areas of behavioral neuroscience.

  • vmPFC supports extinction while cACC supports increased aversive processing.

    “A closely related domain of research on conditioning and extinction in both rodents and humans also suggests that ventromedial PFC (vmPFC), an area neighboring rACC, supports extinction while cACC supports increased aversive processing (Milad and Quirk, 2012; see Figure 7).”

    From Top-Down Dysregulation—From ADHD to Emotional Instability (2016) · cites this paper as Milad and Quirk, 2012

    The section on the human vmPFC reports that its activation correlates with extinction recall. The section on the dorsal anterior cingulate reports dACC involvement in conditioned fear expression and responses to aversive stimuli, but the paper does not identify that region as cACC or establish a broader role in increased aversive processing.

  • The vmPFC is proposed to be the homologue for the IL in rodents and serves to inhibit threat responses produced by the amygdala.

    “The vmPFC is proposed to be the homologue for the IL in rodents [87] and serves to inhibit threat responses produced by the amygdala.”
  • vmPFC modulates amygdala processing of conditioned fear by suppressing fear responses.

    “The vmPFC is thought to modulate amygdala processing of conditioned fear by suppressing fear responses through a set of amygdala neurons in the intercalated region between the basolateral and central amygdala nucleus (Milad and Quirk, 2012).”

  • The vmPFC is activated during retrieval of extinction learning and down-regulates the amygdala.

    “The vmPFC is activated during retrieval of extinction learning and down-regulates the amygdala”
  • In PTSD, there is both hyperactivation of the fear expression and hypoactivation of the extinction memory networks.

    “Therefore, in PTSD, there is both hyperactivation of the fear expression and hypoactivation of the extinction memory networks [59, 60].”

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.
