what is this 24 hr eeg thing where you walk around with it attached to your head? can someone explain what it was like to wear one. how would it work since the other eeg they always told me to stay still and not move my hands or things like that. how can this get an accurate reading. what if you touch something and it sends an electric shock. would that mess up the test? sometimes that happens to me when I touch a doornob and I get a shock on my hand.
