A new study from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) found two clusters of brain cells that compete to promote the persistence or disappearance of traumatic memories. The study, conducted with mice, examined clusters of neurons and found two clusters that promote either a fear response or an extinction of the memory. Researchers also found that the clusters compete with one another to determine the strength of each memory.
