A month or so ago (I can't remember the date) Graham participated in an experiment. They flashed faces on a screen and as he watched they measured his brain waves with the net thing you see here. Fortunately, they recognized that parents would want a photo record of this. G didn't seem to mind the net thing once they got it on him. Each sensor has a sponge tip that had been dipped into salt water. The only thing that bothered him was the salt water running into his eyes. He did well with the experiment; he was reponsive and patient.
