Brain recalls old memories via new pathways

NIH-funded researchers have discovered that an old fear memory is recalled by a separate brain pathway from the one originally used to recall it when it was fresh. Uncovering new pathways for old memories could change scientists’ view of post-traumatic stress disorder, in which fearful events occur months or years prior to the onset of symptoms.
