Mice Can No Longer Remember Elephants Being Afraid Of Them
Remember those movies that show devices used to erase the mind? Well, now researchers may be one step closer to that process. Scientists have now been able to remove certain memories from mice.
“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.”
Dr. Tsien and his team were able to remove new and old memories by over-expressing a protein critical to brain cell communication just as the memory was recalled.
