Just wow. These results can be boiled down to "neurons fire in a given pattern consistently when presented with the same stimulus." That is all. No, really. Also, if you read the methods, there is no proof for a grandmother cell; they merely look at the neurons activated by a stimulus, pick one, and roll with it; there is NO EVIDENCE for convergence here. Yes, we can control SOME neurons' firing pattern, that's the POINT. Saying this is like saying "the pilot of an aircraft directly controls the current in the wire that leads to the servo on the middle flap of the wing!!!! OH GOD BREAKTHROUGH DATA!" umm... I guess you could see it that way..? Seriously, either some horrid science journalism here, or someone needs to get their tenure removed, and I definitely expect the former.
