Scientists Turn Bad Memories Into Good Inside the Brains of Mice
"Neuroscientists have devised a technique for switching the emotional association of a memory from bad to good by directly manipulating the neurons that encode it.
If that sounds like a promising therapy for disorders like PTSD, you’ll have to wait. The experiments were done in mice, and the methods, which include genetically altering neurons and inserting an optical fiber into the brain, won’t be used in people anytime soon (if ever). But this study and others like it are illuminating the neural mechanisms of memory in unprecedented detail, and showing that it’s possible to activate, alter, or even create memories just by tweaking the right neurons.”
