Abstract

Learning to predict rewards based on environmental cues is essential for survival. The orbitofrontal cortex (OFC) contributes to such learning by conveying reward-related information to brain areas such as the ventral tegmental area (VTA). Despite this, how cue-reward memory representations form in individual OFC neurons and are modified based on new information is unknown. To address this, using in vivo two-photon calcium imaging in mice, we tracked the response evolution of thousands of OFC output neurons, including those projecting to VTA, through multiple days and stages of cue-reward learning. Collectively, we show that OFC contains several functional clusters of neurons distinctly encoding cue-reward memory representations, with only select responses routed downstream to VTA. Unexpectedly, these representations were stably maintained by the same neurons even after extinction of the cue-reward pairing, and supported behavioral learning and memory. Thus, OFC neuronal activity represents a long-term cue-reward associative memory to support behavioral adaptation.

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.
