New research from the University of Southampton has demonstrated that it is possible for brain-to-brain (B2B) communication through the power of thought— with the help of electrodes, a computer and Internet connection.
This experiment goes a step further from Brain-Computer Interfacing (BCI) that captures brain signals and translates them into commands, says Dr Christopher James from the University’s Institute of Sound and Vibration Research.
It involved one person using BCI to transmit thoughts, translated as a series of binary digits, over the internet to another person whose computer receives the digits and transmits them to the second user’s brain through flashing an LED lamp.
While attached to an EEG amplifier, the first person would generate and transmit a series of binary digits, imagining moving their left arm for zero and their right arm for one. The second person was also attached to an EEG amplifier and their PC would pick up the stream of binary digits and flash an LED lamp at two different frequencies, one for zero and the other one for one. The pattern of the flashing LEDs is too subtle to be picked by the second person, but it is picked up by electrodes measuring the visual cortex of the recipient.
The encoded information is then extracted from the brain activity of the second user and the PC can decipher whether a zero or a one was transmitted. This shows true brain-to-brain activity.
