Brain mechanisms of fear extinction: historical perspectives on the contribution of prefrontal cortex

Sotres-Bayon, Francisco, Cain, Christopher K., LeDoux, Joseph E.·2006·Biological Psychiatry

Abstract

What brain regions are involved in regulating behavior when the emotional consequence of a stimulus changes from harmful to harmless? One way to address this question is to study the neural mechanisms underlying extinction of Pavlovian fear conditioning, an important form of emotional regulation that has direct relevance to the treatment of human fear and anxiety disorders. In fear extinction, the capacity of a conditioned stimulus to elicit fear is gradually reduced by repeatedly presenting it in the absence of any aversive consequence. In recent years there has been a dramatic increase in research on the brain mechanisms of fear extinction. One region that has received considerable attention as a component of the brain's extinction circuitry is the medial prefrontal cortex (mPFC). In the present article, we review the historical foundations of the modern notion that the mPFC plays a critical role in emotional regulation, a literature that was largely responsible for studies that explored the role of the mPFC in fear extinction. We also consider the role of the mPFC in a broader neural circuit for extinction that includes the amygdala and hippocampus.

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?

  • CBT and exposure are thought to be effective by increasing inhibitory control over aversive salience-driven processing, and ABM training may augment their effects by further supporting these processes.

    “Both CBT and exposure are thought to be effective by increasing inhibitory control over aversive salience-driven processing [77,78], and ABM training may therefore augment their effects by further supporting these processes.”
  • Fear extinction resulting from threat exposure is thought to depend on increasing the inhibitory effect of frontal brain regions on subcortical (amygdala) regions involved in fear learning and threat-salience evaluation.

    “Fear extinction, which results from threat exposure, is thought to depend on increasing the inhibitory effect of frontal brain regions, which support top-down cognitive control, on subcortical (amygdala) regions involved in fear learning and threatsalience evaluation (e.g., Bishop, 2007;Sotres-Bayon, Cain, & LeDoux, 2006).”
  • The hippocampus has strong reciprocal connections with the mPFC and the amygdala; these three brain regions seem to interactively coordinate the encoding and expression of fear extinction.

    “The hippocampus has strong reciprocal connections with the mPFC and the amygdala; these three brain regions seem to interactively coordinate the encoding and expression of fear extinction (Sotres-Bayon et al, 2006).”

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.
