Yesterday they wired me up for an EEG. It was fine to have to wear wires on my head for 24 hours, and they were not that uncomfortable. The removal of the little sensors was definitely one of the worst experiences that I have ever had. Each one was glued on wit something that smelled like Duco cement. In order to take them off, they had to soak them with acetone, it was like having a shampoo with nail polish remover.
