Scientists Flip Mouse Memories From Mad to Glad
Going to your happy place may soon be a breeze. Researchers have manipulated mouse brain circuits to switch bad memories into good ones. The method used, optogenetics, manipulates modified neurons with light and “is revolutionizing research on brain activity,” helping to “establish causal links between brain circuitry and disease symptoms, which could lead to highly targeted, effective therapies,” says OZY’s Melissa Pandika. Scientists have already used optogenetics to induce and relieve OCD- and Parkinson’s-like symptoms, seizures and addiction in animal models.
