Scientists have found a way to send brain-to-brain messages using brainwaves connected to computer technology.

A team of researchers from the University of Barcelona in Spain, Axilum Robotics in France, Harvard Medical School and Starlab Barcelona in Spain used EEG headsets to record the electrical activity in the brain related to the formulation of the words ‘hola’ and ‘ciao.’ A computer then converted these messages into binary and used electrical stimulation to implant the information into the receiver’s mind, which then appeared as specific flashes of light in the corner of their vision. The "telephathic" greeting was sent from subject in Thiruvananthapuram, India to another in Strasbourg using only brain-power.

Our brains consist of billions of active neurons, all of which are in dendritic contact with other neurons, so the total number of neurological interconnections is around 1014(100 trillion). The total length of the nerve dendrites in an adult brain is over 105,600 miles (170,000 km).Our thoughts generate electrical impulses which are created by chemical reactions between the neurons; these impulses, which can travel as fast as 170 miles per hour, can be measured in a process known as electroencephalography (EEG).

Astonishingly, this process has been medically possible since 1924, and certainly this is not the first time that brain-wave sensing equipment has been used, as previous experiments have analysed the signals and fed them into a computer interface that used the "mind-power" to control actions in everything from helicopters to computer game avatars. In the latest study, which was published in Plos One, electroencephalography (EEG) headsets were used to record electrical activity from neurons in the brain that were created when the words ‘hola’ and ‘ciao’ formed the basis of the subject’s thought.

The researchers went one step further than previous tests, however, and replaced the computer interface with another brain to receive the signals.A computer translated the message and then used electrical stimulation to implant it in the receiver’s mind, where it appeared as sequences of light that could be decoded by the receiver. The experiment was repeated with different subjects, and thought messages were sent successfully between other "transmitters" and "receivers" in Spain and France.

The study authors believe that mind-controlled messages could become commonplace in the near future:

‘We anticipate that computers in the not-so-distant future will interact directly with the human brain in a fluent manner, supporting both computer- and brain-to-brain communication routinely,’ they wrote.
