Memories selectively, safely erased from mice.

From the Medical College of Georgia:

New and old memories have been selectively and safely removed from mice by scientists.

"While memories are great teachers and obviously crucial for survival and adaptation, selectively removing incapacitating memories, such as traumatic war memories or an unwanted fear, could help many people live better lives," says Dr. Joe Z. Tsien, brain scientist and co-director of the Brain & Behavior Discovery Institute at the Medical College of Georgia School of Medicine.

"Our work reveals a molecular mechanism of how that can be done quickly and without doing damage to brain cells," says the Georgia Research Alliance Eminent Scholar in Cognitive and Systems Neurobiology.

Dr. Tsien's research team, in collaboration with scientists at East China Normal University in Shanghai, were able to eliminate new and old memories alike by over-expressing a protein critical to brain cell communication just as the memory was recalled, according to research featured on the cover of the Oct. 23 issue of Neuron.
