The paper shows that (1) contextual amnesia, produced by the optogenetic inhibition of hippocampal activity (dCA1) during stress, causes PTSD-like hypermnesia in mice, and (2) the re-contextualization of traumatic memory by re-exposure to all trauma-related cues cures PTSD-like memory while promoting normal fear memory.
