The Biology Of Induced Memory

Summary:
In 2000, Dr. Karim Nader discovered that a fear memory induced in a rat and reactivated after 1 -12 days of storage in the outer part of the brain could be eradicated with a shot of anisomycin, a protein-synthesis inhibitor. Now, Dr. Nader and his colleague from New York University , neuroscientist Joseph E. Ledoux, report that the same reconsolidation process goes on in another part of the brain which mediates conscious memories, the hippocampus.

"Imagine the possible benefit for people traumatized by haunting memories of terror or tragedy. The day may come when the cure is recalling the trauma, and then erasing it with a shot", wondered Dallas Morning News reporter Tom Siegfried (Aug. 28, 2000) commenting on Dr. Karim Nader's discovery that a fear memory induced in a rat and reactivated after 1 -12 days of storage in the outer part of the brain could be eradicated with a shot of anisomycin, a protein-synthesis inhibitor.
