Scientists from the University of Washington were able to connect two brains from two distant places without any verbal communication with the use of the internet. The research study has been published in the popular science journal PLOS ONE.

According to NWR, Andrea Stocco, Assistant Professor of Psychology in the University of Washington and the lead author of the study, has shared that experiment used visual conscious experiences via signals, constituting a process that needs two individuals to collaborate.

"This is the most complex brain-to-brain experiment, I think, that's been done to date in humans," said Stocco.

The first research in this subject has been carries out by Rajesh Rao, Professor of Computer Science and Engineering, Universoty of Washington along with Stocco and Chantel Prat, faculty member at the Institute of Learning & Brain Sciences and associate professor of psychology in the University of Washington to determine how to link two human brains together.

According to Pulse Headlines, the experiment was carried out in laboratories that were located miles apart and employed five pairs of participants to play twenty rounds of questions and answers game.

 In the game experiment, one of the participants in the pair had to wear a cap connected to an EEG (electroencephalography) machine that recorded electrical brain activities. Then the other participant in the pair was shown an object on the computer and the inquirer saw a list including possible items along with a couple of related questions. The inquirer sent questions simply by clicking the mouse, and the respondent needed to response in "yes" or "no" just by concentrating on any one of the two LED light (flashing at diverse frequencies) flashing on the monitor.

The results revealed that the participants were able to guess the correct object in 72 percent of the real games as compared to the 18 percent of the control rounds. Scientists believe that the incorrect guesses could be driven by many factors such as the uncertainty about whether a phosphene had appeared.

"They have to interpret something they're seeing with their brains. Imagine having someone with ADHD and a neurotypical student. When the non-ADHD student is paying attention, the ADHD student's brain gets put into a state of greater attention automatically," said co-author Prat.
