Encoding of fear learning and memory in distributed neuronal circuits

Herry, Cyril, Johansen, Joshua P·2014·Nature Neuroscience

Abstract

How sensory information is transformed by learning into adaptive behaviors is a fundamental question in neuroscience. Studies of auditory fear conditioning have revealed much about the formation and expression of emotional memories and have provided important insights into this question. Classical work focused on the amygdala as a central structure for fear conditioning. Recent advances, however, have identified new circuits and neural coding strategies mediating fear learning and the expression of fear behaviors. One area of research has identified key brain regions and neuronal coding mechanisms that regulate the formation, specificity and strength of fear memories. Other work has discovered critical circuits and neuronal dynamics by which fear memories are expressed through a medial prefrontal cortex pathway and coordinated activity across interconnected brain regions. Here we review these recent advances alongside prior work to provide a working model of the extended circuits and neuronal coding mechanisms mediating fear learning and memory.

  • The amygdala is central to a distributed neural circuitry orchestrating Pavlovian fear conditioning in humans and other species.

    “The amygdala-an ensemble of functionally distinct nuclei located in the medial temporal lobe-is central to a distributed neural circuitry orchestrating Pavlovian fear conditioning in humans and other species, underscoring its crucial role in promoting reproductive fitness (Herry and Johansen, 2014).”

  • Activity in pathways from the mPFC and vHPC to the BLA can both directly invigorate the anxiety response and influence the likelihood of a threat appraisal.

    “Activity in these pathways can both directly invigorate the anxiety response (for example, through projections of the vHPC to the lateral septum and hypothalamic nuclei; see below), as well as influence the likelihood of a threat appraisal (for example, through fear-memory retrieval via mPFC projections to the amygdala; see below and ref. 69).”

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.
