The headline, “Scientists Prove that Telepathic Communication is Within Reach,” excited me. The actual details of the experiment disappointed with their really crude and blunt implementation.
Pascual-Leone’s experiment was successful—the correspondents neither spoke, nor typed, nor even looked at one another. But he freely concedes that the test was more a proof of concept than anything else, and the technique still has a long way to go. “It’s still very, very early,” he says, “[but] we can show that this is even possible with technology that’s available. It’s the difference between talking on the phone and sending Morse code. To get where we’re going, you need certain steps to be taken first.”
Indeed, the process was drawn out, if not downright inelegant. First, the team had to establish binary-code equivalents of letters; for example “h” is “0-0-1-1-1.” Then, with EEG (electroencephalography) sensors attached to the scalp, the sender moved either his hands or feet to indicate a 1 or a 0. The code then passed to the recipient over email. On the other end, the receiver was blindfolded with a transcranial magnetic stimulation (TMS) system on his head. (TMS is a non-invasive method of stimulating neurons in the brain; it’s most commonly used to treat depression.) The TMS headset stimulated the recipient’s brain, causing him to see quick flashes of light. A flash was equivalent to a “1” and a blank was a “0.” From there, the code was translated back into text. It took about 70 minutes to relay the message.
A journey of a thousand miles begins with a single step, I suppose.
