It’s a first for neuroscience, scientists have created an electronic link between the brains of two rats. They demonstrated that signals from the mind of one can help the second solve basic puzzles in real time — even when those animals are separated by thousands of miles.
Here’s how it works. An “encoder” rat in Natal, Brazil, trained in a specific behavioral task, presses a lever in its cage it knows will earn it a reward. A brain implant records activity from the rat’s motor cortex and converts it into an electrical signal that is delivered via neural link to the brain implant of a second “decoder” rat.
