Amygdala-Prefrontal Synchronization Underlies Resistance to Extinction of Aversive Memories

Abstract

Emotional memories can persist for a lifetime but can also undergo extinction. Although we know about the mechanisms involved in expression and extinction, we know very little about the mechanisms that determine whether a specific memory would persist or not. Here, we use partial reinforcement extinction effect (PREE) to explore the neural mechanisms that differentiate persistent from labile memories. We recorded the simultaneous activity of neurons in the amygdala and the dorsal anterior cingulate cortex (dACC) while monkeys engaged in tone-odor aversive conditioning. We report that under continuous reinforcement schedule (ConS), activity in the amygdala precedes behavioral response, whereas under partial schedule (ParS), dACC activity precedes it. Moreover, we find that ParS induced cross-regional pairwise correlations throughout the entire acquisition session, and their magnitude and precision predicted the later resistance to extinction. Our results suggest that memory persistence depends on distributed representations and, specifically, resistance to extinction of aversive memories is maintained by correlated amygdala-dACC activity.

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.
