People are about to manipulate dreams

The hope of transforming dreams according to human wishes has taken a step closer to reality, when American scientists have the ability to manipulate what the rats 'see' during sleep.

Scientists have discovered that, during sleep, an area in the human brain called the codex that functions to 'show' the events of the day in a cycle can help reinforce memories of 'suffering' . The same thing was discovered in dream mice running through mazes after a day of activity in the lab at Massachusetts Institute of Technology (MIT).

In the new MIT study, researchers Matthew Wilson and Daniel Bendor used sound signals to train mice to run through a maze. Accordingly, a sound guides the experimental animals to the reward to the right of the track and the other sounds direct them to the reward on the left.

The brains of experimental mice showed specific types of activation of certain neuronal neurons in the coding region, depending on whether they ran to the right or left of the labyrinth. These neurons inform mice about the position of space as well as create certain types of activation when the mouse changes position.

When the mice slept, the team re-analyzed neurological activity in the area of ​​the code. During sleepless REM sleep, the team gives a random sound every 5 to 10 seconds, including two sounds that are attached to the two sides of the labyrinth. ' When the sound attached to the left side of the labyrinth is chanted, the dream content is transferred to the memories of running down the left side of the labyrinth. Similarly, when the sound attached to the right is heard, the dream content is moved to the right side of the maze '.

Even if the sounds are played in less than 1 second, the dream content will still appear for 5-10 seconds.'Therefore, the sounds do not simply guide the content of the dream, but also seem to delimit or choose memories that will be re-expressed later,' Wilson said on Live Science.

The phenomenon does not appear when the mice are awake and not in the labyrinth.

Results of Wilson's study showed that humans can change memories during sleep. This opens up the prospect of more extensive control of the 'memory consolidation' process during sleep to mistakenly highlight selected memories and prevent or change unwanted memories.
