Abstract

The lateral nucleus of the amygdala (LA) is the first site in the amygdala where the plasticity underlying fear conditioning could occur. We simultaneously recorded from multiple LA neurons in freely moving rats during fear conditioning trials in which tones were paired with foot shocks. Conditioning significantly increased the magnitude of tone-elicited responses (often within the first several trials), converted unresponsive cells into tone-responsive ones, and altered functional couplings between LA neurons. The effects of conditioning were greatest on the shortest latency (less than 15 ms) components of the tone-elicited responses, consistent with the hypothesis that direct projections from the auditory thalamus to LA are an important link in the circuitry through which rapid behavioral responses are controlled in the presence of conditioned fear stimuli.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Lateral amygdala cells develop robust responses to shock-predictive cues, corresponding to freezing behavior when the cues are presented.

    “These cells develop robust responses to shock-predictive cues, corresponding to freezing behavior when the cues are presented71.”

    From Resolving the neural circuits of anxiety (2015) · cites this paper as [71]

  • Several lines of indirect evidence support the idea that this plasticity occurs as a result of a Hebbian mechanism through which depolarization of LA pyramidal neurons by the shock US coincident with weaker activation of the same cells by auditory CS inputs results in fear learning.

    “Several lines of indirect evidence support the idea that this plasticity occurs as a result of a Hebbian mechanism through which depolarization of LA pyramidal neurons by the shock US coincident with weaker activation of the same cells by auditory CS inputs results in fear learning (8–18).”

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.
