Researchers at Duke University School of Medicine have enabled two rats to "communicate" across thousands of miles by sharing electrical impulses delivered using microelectrodes in their brains. In the experiment, an "encoder" rat in Brazil was prompted by a cue light to conduct a simple task. When the brain waves from the first rat were delivered to a "decoder" rat in North Carolina, the second rodent was able to parrot the task without a visual prompt. "This tells us that it could be possible to create a workable network of animal brains distributed in many different locations," said researcher Miguel Pais-Vieira.
