The rat is pinned down. It’s laying prostrate on what looks like a hospital bed with its head in some sort of vice. The rat is white and huge and has a black ribbon tied around the middle of its tail. Now and again, the tail flicks. Unremarkable, right?
Well, yes, except that the rat is having its mind controlled by human thought—and there’s evidence all around that our minds might soon come under control, too.
In April, when researchers from Harvard Medical School published the rat video on YouTube, they were demonstrating the creation of a brain-to-brain interface formed between human and vermin. Basically, the human could concentrate on a specific idea and—via something called transcranial focused ultrasound, or FUS—an impulse would be sent to excite the part of the rat’s brain that controls tail movement. The experiment worked 94 percent of the time, with a thought taking about 1.5 seconds to travel from human to rat.
