Yes, you read it right! This is not the sequel of the movie Eternal Sun Shine Of The Spotless Mind.
Researchers were involved in this process to find the state of memory after knowing that they are stored somewhere. But, the question was ‘where?’.
This was proved by MIT researchers recently. They also proved that by triggering a small cluster of neurons, they were able to force the subject to recall a specific memory. And by removing these neurons, the subject would lose that memory.
To create a fear memory, mice were given an electric shock in the hippocampus region of the brain; then later, using laser light, they activated the neurons where the memory was stored. The mice then quickly entered in a defensive, immobile crouch – which strongly suggests that the fear memory was being recalled.
Here you can understand the whole experiment done by MIT researchers and it’s result in detail:
