Two people sharing the same thoughts may be a matter of understanding or coincidence, but now it is scientifically possible. Neuroscientists have been able to devise a way to connect not two but three brains. It is weird but it is being experimented. The team of researchers hope it would connect new network of people through what they have called a BrainNet. UK Woman Sings Songs and Cracks Jokes With Doctors During Her Brain Surgery! Watch Video.
BrainNet is a system which can eventually connect different minds together and they can probably share their thoughts. It will also help in understanding the functioning of the brain. A combination of electroencephalograms (EEGs), records the brain activity and transcranial magnetic stimulation (TMS). The neurons here are stimulated by the magnetic fields. The researchers describe, "We present BrainNet which, to our knowledge, is the first multi-person non-invasive direct brain-to-brain interface for collaborative problem solving. The interface allows three human subjects to collaborate and solve a task using direct brain-to-brain communication." ‘Brain Passwords’ Could Unlock Your Future Smartphones.
In this experiment, two persons (senders) were connected to ECG electrodes and were asked to play Tetris-style game. In the game, they had to stare at flashing LEDs which were producing different signals the ECG could pick. Now their choice was relayed through a third person (receiver) mind. Now although this receiver could not see the whole game, they were able to rotate the flashing light. The researchers tried it with 5 groups consisting of 3 people each and they were 81.25% accurate.
The current system can transmit just one bit of data at a time but the scientists think they can expand it in future. The group has successfully connected two brains effectively. "Our results raise the possibility of future brain-to-brain interfaces that enable cooperative problem solving by humans using a 'social network' of connected brains," says the team of researchers.
