Connecting the brain that helps people share their thoughts has become a real technology!

Simply called, it's the ability to share thoughts. In fact, the ability to store and share direct thoughts is also exploited by film makers quite a lot - mainly in fantasy movies. But have you ever thought about this skill appearing in real life?

So there it is. Recently, neurologists from Washington University and Carnegie Mellon University (USA) have successfully connected the brains of three people, allowing them to share thoughts together. Although it is only in a game that simulates Tetris, experts believe that when done on a large scale, we can create a network to share thoughts among people.

BrainNet can later connect more brains, even through the internet environment.

The system, called BrainNet , works by combining electroencephalogram (EEG) to record brain activity, and electromagnetic stimulation through the skull (TMS) to affect the nervous system. As expected, BrainNet can later connect more brains, even through the internet environment.

But not only that, BrainNet also believes that this technology can enhance our understanding of the human brain, at a deeper level.

"Please introduce BrainNet, which we know is the first system that can connect many people's thinking without invasion to solve collaborative issues" - quoted in the report. researchers.

"3 people - 3 separate brains can combine and solve puzzles through brainstorming and communication technology".

Specifically in the experiment, two people - called "senders" - connect to EEG electrodes, and are asked to play a jigsaw puzzle. They will have to decide whether the blocks on the screen should be rotated or not.

Experts believe that this is the technology of the future.

To send signals, both are asked to look at one of the two LEDs located at the top of the screen. Flashes with 2 different frequencies: 15 Hz and 17 Hz. Another frequency is that the signal sent to the brain is different, and the EEG can be distinguished.

The other is "recipient" . This person will receive the signal via TMS nodes with the ability to receive signals sent by the other two. The recipient will not be able to see the screen, but will know whether to rotate the blocks through the two received signals.

The experiment was performed on 5 groups of 3 people, and the exact ratio reached 81.25% right on the first try - a very high rate.

To increase complexity, "sender" can transmit additional feedback whether or not "recipient" has done it properly. As a result, the recipient can even distinguish who the signal is coming from, and who makes the right decisions.

The current system can only transfer 1 bit of information each time, but experts believe that this is the technology of the future. In fact, brain-connected technology has been successfully implemented by a group of scientists before, but only on 2 brains.

"Our research results open a future that allows people to connect and share thoughts together, even creating a social network that connects the human brain" - cited in the research report.
