“I wish I could explain things more properly. Just couldn’t find the right words, or maybe I could just transfer the idea in my head into your head. So that you could have at least explained it well. You know just a brain to brain communication.”

Has this ever happened to you?? The language was invented in the first place for the purpose of communication. It allowed people to communicate that means it was a medium of conveying what one person thinks to another. That was the basic idea right?? With time people advanced with this too there came into being almost 19,500 languages in India alone. Later on, translation became a profession. Translators helped people translate and understand a foreign language.

What if the need for translation ends?? the need for the language itself ends?? What if we actually find a way of passing the idea in one brain into another directly?? These what ifs now have an answer. Brain to Brain communication.

What is the brain to brain communication?

Brain to brain communication is the same as the name suggests, connecting brains with each other to establish a communication. Brain to brain communication enables a person to directly transfer the thoughts of himself into the person he is connected with without the use of language or gestures.

How will this happen??

 It basically works with the help of electroencephalograms (EEGs) and transcranial magnetic stimulation (TMS). EEGs to record the electrical impulse, the presence of impulse indicates brain activity and the TMS to simulate the neurons using magnetic fields.

The recent experiment included connecting 3 people far away from each other. Two of whom were senders and the third person was a receiver. They were made to play a game of Tetris. The senders were connected to the electrodes. The senders could see the game but think about the probable rotations required in the game. The receiver could only rotate the parts but could not see the game.

In this setup, the senders saw the game and sent the impulse of rotations to the receiver. The sender had to look at two light sources for transmitting their thought. These led lights created the impulse in the brain that the EEGs could capture. These impulses were then sent to the receiver through a TMS cap. The TMS cap could generate flashes of light in the receiver’s brain. These are called phosphenes.

Complexity addition

This experiment gained an accuracy rate of 81.25% which is very decent. In the later parts of the experiment, the researchers added a feedback round. In this round, the sender could send an impulse to the receiver telling if he made the correct move. Using this mechanism the receiver could decide the reliability of the sender. This complexity addition assured the application of this brain to brain communication for real-world problems too.

Previous experiments

The previous experiment connected two people. The scientists made two people play a game of 20 questions against each other. They used flashes to indicate yes and no. As of now, the experiment is only limited to the transfer of bits and flashes but researchers aim to improve it further very soon.


 This is definitely not fully reliable and a slow process now. The neuroscience community is yet to review it. In the future, the brain to brain communication can also tackle and solve problems without much chaos. This experiment has literally broken down the only barrier of communication and had laid the path to a better future ahead.
