B.F. Skinner only used food pellets with his subjects. He did not implant
anything into the brain of his animals. A "Skinner Box" is just a box that
has levers in it, when one of the levers is pressed, a food pellet is
released. Skinner studied classical and operant conditioning, he was not a
biologist researching the brain.
Someone else must have used Skinner's work for inspiration that led to
direct stimulation.
