Talk Title: The eternal sunshine of the fearless mind - Recent insights into remote fear memory attenuation
Abstract: Fear and traumata generate some of the longest-lived memories, which contributes to the elevated life-time prevalence of stress and anxiety-related disorders. Despite the corresponding need to better understand how such long-lasting fear memories can be attenuated, surprisingly little is known about this process. In this talk, I will present our recent efforts that help to better understand remote fear memory attenuation from a circuit, cellular and molecular perspective. These findings have revealed that remote fear memory attenuation is mediated by the re-engagement of the original memory trace of fear, rather than its suppression; and that the attenuation of remote fear memories relies on a different circuitry than that of recent ones.
