        Memory Hackers | Manipulating Memories with Optogenetics

        Learn about optogenetics, a revolutionary technique to map and manipulate memories using lasers, in this video from NOVA: Memory Hackers. Neuroscientist Christine Denny demonstrates the science, which has potential human applications. She puts a mouse in a new environment, causing it to act scared. Then, Denny flicks a switch that shines light over a specific area of the mouse’s brain. The light triggers brain cells to retrieve a pleasant memory imprinted in the mouse’s brain, and the mouse feels safe. When Denny turns off the laser, the memory ceases and the mouse returns to its frightened state. This resource is part of the NOVA Collection.
