By manipulating a single protein found in the brains of mice, researchers can wipe out a mouse’s specific, traumatic memory without damaging brain cells, a new study reports. While the process is nowhere near ready for testing in humans, researchers say it does raise the possibility of novel treatments for post-traumatic stress disorder and other mental health conditions. “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,” said [lead researcher] Joe Tsien [Telegraph].
Humans have the same so-called “memory molecule” in our brains, and the announcement is certain to prompt speculation that sci-fi scenarios of memory erasure are almost upon us. The concept was the premise of the popular 2004 film Eternal Sunshine of the Spotless Mind, in which two former lovers pay a “memory-erasure” service to expunge the unhappy affair from their minds [HealthDay News].
