Researchers at the University of Washington have experimented with a brain-to-brain connection which allowed pairs of participants to transmit answers to questions from one person to the other using their brain signals and the Internet. This experiment was done in darkened rooms within two of the university's labs that are located a mile apart and involved five pairs that played 20 rounds of the question-and-answer game. The participants were able to provide the correct answers 72% of the time.
Although the experiment did not produce perfect results, this breakthrough already has a lot of potential which can lead to further studies in the future. The research team at the University of Washington is also working to transmit various brain states, which will further expand their study on the effectiveness of transmitting brain signals.
