Researchers connect brains subjects via http




Researchers have succeeded in connecting the brains of different subjects via http. As a result, one test subject was able to think of the firing of a gun in a game, after which the hand of the other test subject was that actually do so.

A regular EEG recorded the commands that the subjects gave, after which the signal went via http to a different test subject, which by means of a helmet, the signals received in a blind chamber. The transmitter watched a computer game, but the controls of the gun went through another subject who did not see the game. He had, however, push the button to fire a cannon. Sending and receiving signals went through computers.

The movement is possible because the command stimulates the motor cortex of the brains of the recipient. This part of the brain is responsible for the control of the muscles. The brains of the second test subject were stimulated with transcranial magnetic stimulation. With this technique, the person is given a type of helmet, by which the stimulation can penetrate the skull. Eventually, the system ensured that the second test person involuntarily moved his finger on a keyboard.

That was not always good, according to the study by researchers at the University of Washington in the United States and which was published in the scientific journal Plos One. In some subjects it went well in 83 percent of cases, but in another couple that succeeded but in a quarter of cases.

According to the researchers, it is the first time that anyone could immediately send a signal with a command to the brain of another, although the same researchers last year in a pilot did. Next steps according to the scientists to allow brain-to-brain communication from one person to many people or conversely, that many people can give commands to one person.
