Optogenetics

Optogentics is a new technique by which one can replay sweet memories on demand. The scientists at the MIT have claimed that it is possible to activate a memory on demand by stimulating only a few neurons of our brain with light. Optogenetics, is a medium that shows memories reside in specific cells in the brain and that they can be turned on. This research has given scientists a new way to explore myriad questions — how memories are preserved and recalled, and how they can erode over time.
