When the cells can’t be reactivated, forgetting happens – that means reminiscences are usually not misplaced, they’re nonetheless there, however the mind doesn’t give us entry. “The speed of forgetting” apparently is determined by circumstances in an ever-changing world.
“It’s as if the reminiscences are saved in a secure however you possibly can’t bear in mind the code to unlock it,” the scientist stated.
