Abstract

Although the basolateral amygdala (BLA) is known to play a critical role in the formation of memories of both positive and negative valence, the coding and routing of valence-related information is poorly understood. Here, we recorded BLA neurons during the retrieval of associative memories and used optogenetic-mediated phototagging to identify populations of neurons that synapse in the nucleus accumbens (NAc), the central amygdala (CeA), or ventral hippocampus (vHPC). We found that despite heterogeneous neural responses within each population, the proportions of BLA-NAc neurons excited by reward predictive cues and of BLA-CeA neurons excited by aversion predictive cues were higher than within the entire BLA. Although the BLA-vHPC projection is known to drive behaviors of innate negative valence, these neurons did not preferentially code for learned negative valence. Together, these findings suggest that valence encoding in the BLA is at least partially mediated via divergent activity of anatomically defined neural populations.

  • Basolateral amygdala microcircuits separate reward and aversion, with valence coding that can bias motivated action toward appetitive cues through projections to the accumbens and toward aversive cues through projections to the central nucleus of the amygdala.

    “They [29,30] showed parsing of reward and aversion in basolateral amygdala microcircuits. Specifically, they provided evidence of valence coding in the basolateral amygdala, that could bias motivated action to appetitive cues via projections to the accumbens and to aversive cues via projections to the central nucleus of the amygdala.”

  • There is relatively little collateralization of BLA projection neurons to their target regions, suggesting a high degree of projection specificity.

    “Notably, there appears to be relatively little collateralization of BLA PNs to these target regions (17), suggesting a high degree of projection specificity.”
  • BLA projection neurons innervating the nucleus accumbens and ventral hippocampus primarily encode information with positive and negative valence, respectively.

    “This work has, for instance, proposed that BLA PNs innervating the NAc and vHPC primarily encode information with positive and negative valence, respectively (17,20,22,23).”
  • BLA projection neurons projecting to the ventral hippocampus or nucleus accumbens have been shown to sparsely innervate the dmPFC.

    “Moreover, BLA PNs projecting to the vHPC or NAc have been shown to sparsely innervate the dmPFC (17).”
  • Anticipatory licking during the CS-trace provides a reliable, trial-by-trial index of memory expression.

    “in which anticipatory licking provides a reliable, trial-by-trial index of memory expression.”

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.
