The scientists were able to introduce false memories in the brains of mice





Do you think that the opportunity to get into the brain and implanting it in other people’s memories can be found only in science fiction, like nolanovskogo “Elements”? Until recently, all was well until scientists from the Massachusetts Institute of Technology have found, and then successfully implanted false memories in the brain of a laboratory mouse. In this case, the mouse began to see those memories as if they were really real.

“It does not matter whether they are true or false memories, the process of memory is always working on the same principle,” – said Susumu Tonegawa, a professor of neurology and head of the research.

The subsequent experiment showed that the penetration of foreign intelligence is not just a cool story for some sci-fi movie or a book. Now it is not.

The experiment began with the fact that a few rodents placed in a condition to which they were not familiar with, and allowed them to explore them. Meanwhile, through genetic engineering, scientists tagged cells responsible for the emergence of new memories chennelrodopsinom – a protein that illuminates the neurons when exposed to a special light.

The mice were then placed in another cell, where they experienced a slight shock. At that moment, when the mice experienced a shock, scientists using light, found those memory cells that contained the details of the first chamber and “turned” them. In other words, being in a state of shock in the chamber B, the mice began to use the memories of being in the chamber A.

After three days, when the mice were placed back into the first chamber, rodents showed signs of fear, although, as noted above, no annoying factor it was not. This confirmed that the mice were false memories that never happened to them in the chamber A.

“This study shows how we believe, the first case of successful implementation, or, if I may say so, a false memory implanted in the mouse brain” – the scientists say.

Further experiments, according to scientists, to better describe the understanding of the question of how false memories are formed in the human brain.
