Korean researchers have developed a method that allows two brains, one of a human subject and a of a rat, to each other can be linked. This would not need surgery.
A lot of interfaces between a computer and the brain or other neural structures take a surgery for electrodes implantation. Moreover, such interfaces are generally uni-directional; signals from the brain are read by a computer, or a computer sends impulses to brain or muscles. Researchers from a Korean university, however, have a bi-directional interface has been developed, which are brain signals of a person to the brain of a rat sends.
The signals of the human subject via an eeg read-out. The subject had to have a monitor to look, what the desired brain activity caused. That activity with electrodes on the head is collected and processed by a computer. The rat was a different technique, based on ultrasound, used for specific parts of the brain to stimulate. The fus-generator was aimed at the brain area that the tail of the rat.
When the correct stimulus was the human-generated hersensignaal that way through a computer to the rattenhersenen be sent, which resulted in the movement of the tail. Between the two signals is approximately one and a half second delay, but the research would be the impetus for a brain-to-brain interface.
