A device for broadcasting electrical signals from the brain of an animal is described. It is small enough to be implanted under the animal's skin. That signals are broadcast without distortion is shown by the comparison of a broadcast recording of an electrocorticogram of a cat with a simultaneous recording made directly with wire leads.
