competition between engrams influences fear memory formation and recall
Copyright policy )competition between engrams influences fear memory formation and recall
How to link and separate memories Engrams are the changes in brain tissue that store single memories. Neuroscientists can localize and manipulate them, but until now, little was known about how multiple engrams interact to influence memories. Rashid et al. examined how neural assemblies in an area called the lateral amygdala interact. If two frightening events occurred within 6 hours, the same set of neurons was used to express fear memories for both events. However, if the events were separated by 24 hours, distinct memory traces were formed. Science , this issue p. 383
