My first thought was sex, but I see that’s been covered. My second thought is, I’m not sure this is what it first sounds like. They put the TMS coil directly over the part of the receiver’s brain that controls hand movement, and it sounds like that’s the only reason the receiver moved his right hand instead of responding in some other way. So it sounds like the fact that the movement the sender was thinking of was similar to the movement the receiver performed was just a trick of the setup, and that all that was transmitted was a one-bit signal. The really exciting applications (ahem) will have to wait until the signal being transmitted is related to the action to be performed.
