In a study that sounds like it was ripped straight out of a sci-fi movie, researchers at Harvard have created the first noninvasive brain-to-brain interface between a human and…a rat. All the human connected to the machine has to do is think and he can control the motion of the rat’s tail. While nowhere near as staggering as a connection between two human brains, this is definitely an important step in that direction.
