In the experiment, conducted by researchers from Duke University, two rats could communicate telepathically with each other thousands kilometers apart, in theory, could pave the way for this technology for humans.
Rats were connected via brain implants. One of them had to choose one of the two levers, depending on the color of the lamp lights. Another rat could not see the lamp, but pressed the right lever, receiving electrical impulses from the brain of another rat. The rat did not know that it affects the brain of other rat, it just received its reward.
