The nurse attached a rubber 'hairnet' and then placed little connector blocks under it that connected to Gary's scalp with a special gel. Once she had done this she clipped wires to them. It probably took about 20 minutes.
These wires were connected to the machine that could pick up Gary's brain waves.
Gary was then asked to lay on a couch as some of the tests might bring on a seizure. The tests were quite simple. First he had to close his eyes for two minutes and then open them for two minutes while the nurse took readings. I assume this was to gauge normal brain function. Then he had to do deep breathing for 3 minutes in order to make him hyper-ventilate. Then they flashed strobe lighting in his eyes at various speeds. Luckily/unluckily (depends on which way you look at it) it didn't bring on a fit. Being NHS, Gary won't find out the results for up to six weeks! Oh well, seeing as they probably won't even find anything I suppose it doesn't really matter!
