A Neural Switch for Active and Passive Fear
Open accessAbstract
The central nucleus of the amygdala (CeA) serves as a major output of this structure and plays a critical role in the expression of conditioned fear. By combining cell- and tissue-specific pharmacogenetic inhibition with functional magnetic resonance imaging (fMRI), we identified circuits downstream of CeA that control fear expression in mice. Selective inhibition of a subset of neurons in CeA led to decreased conditioned freezing behavior and increased cortical arousal as visualized by fMRI. Correlation analysis of fMRI signals identified functional connectivity between CeA, cholinergic forebrain nuclei, and activated cortical structures, and cortical arousal was blocked by cholinergic antagonists. Importantly, inhibition of these neurons switched behavioral responses to the fear stimulus from passive to active responses. Our findings identify a neural circuit in CeA that biases fear responses toward either passive or active coping strategies.

“All defense responses in the animal model of the defense cascade—arousal, freezing, flight or fight, tonic immobility, collapsed immobility, and quiescent immobility—are responses to threat mediated by neural circuits involving the extended amygdala, hypothalamus, periaqueductal gray (PAG), ventral pontine tegmentum, ventral and dorsal medulla, and spinal cord.22–25”

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.
