Active Avoidance Requires a Serial Basal Amygdala to Nucleus Accumbens Shell Circuit
Open accessAbstract
Freezing is a species-typical defensive reaction to conditioned threats. While the neural circuitry of aversive Pavlovian behavior has been extensively studied, less is known about the circuitry underlying more active responses to danger. Here we show that the flow of information between the basal amygdala (BA) and the nucleus accumbens (NAcc) is necessary for signaled active avoidance behavior. Rats trained to avoid shock by shuttling during an auditory conditioned stimulus showed increased expression of the activity-dependent protein c-Fos in the NAcc, specifically the shell subregion (NAccSh). Silencing neural activity in the NAccSh, but not in the adjacent NAcc core, disrupted avoidance behavior. Disconnection of the BA and the NAccSh was just as effective at disrupting avoidance behavior as bilateral NAccSh inactivations, suggesting learned avoidance behavior requires an intact BA-NAccSh circuit. Together, these data highlight an essential role for the amygdalar projection to the ventral striatum in aversively motivated actions.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
The source backs part of the claim, not all of it — or backs it for a different population, condition or comparison.
In the citing paper
“The vmPFC is proposed to toggle between these different output paths of the amygdala, shifting the flow of information to promote aversively motivated action instead of Pavlovian freezing responses (Moscarello and LeDoux, 2013; Ramirez et al., 2015).”

“The lateral nucleus also projects to the basal nucleus of the amygdala, which projects to the striatum. These connections are essential for avoidance learning (Amorapanth et al., 2000; Ramirez et al., 2015).”

“However, the basal nucleus of the amygdala is engaged during avoidance learning and may transfer information about CS-US association to the striatum (Amorapanth et al., 2000; Ramirez et al., 2015).”

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.
