Scientists have successfully selected and safely erased specific memories in a mouse’s brain, leaving others intact, it was announced today. The erasure can be done while a mouse tries to retrieve an individual memory, said Joe Z. Tsien, brain scientist and co-director of the Brain & Behavior Discovery Institute at the Medical College of Georgia School of Medicine. “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,” Tsien said.
