While it’s not clear how the method works at a neurological level, the study represents “a really exciting development,” Amy Milton, a behavioral neuroscientist at the University of Cambridge who was not involved in the work, tells STAT. She adds that the findings mark “the first time it’s been shown in a clinical population that this can be effective.”
The study was designed to manipulate the brain’s retrieval and stabilization of memories—in this ...
