World is turning more virtual and less real. Technology is making it possible gradually. Back ago in 90's human can only imagine of super power, artificial intelligence, genetic mutation and etc. But now every single imagination of our fore fathers is turning out to be true.
Scientists at RIKEN-MIT Center for Neural Circuit Genetics have managed to implant artificial memories in mice.

Susumu Tonegawa and colleagues described that they were able to get mice believe that they had been shocked in one place, when it had really happened in one place,when it had really happened it another.

Scientists told that :
We have created a false memory in mice by optogenetically manipulating memory engram–bearing cells in the hippocampus. Dentate gyrus (DG) or CA1 neurons activated by exposure to a particular context were labeled with channelrhodopsin-2. These neurons were later optically reactivated during fear conditioning in a different context. The DG experimental group showed increased freezing in the original context, in which a foot shock was never delivered. The recall of this false memory was context-specific, activated similar downstream regions engaged during natural fear memory recall, and was also capable of driving an active fear response. Our data demonstrate that it is possible to generate an internally represented and behaviorally expressed fear memory via artificial means.
