Hi There babyjane,
I've had a telemetry 3 times. your description is exactly what it is. They glue the wires to your scalp to monitor your brains electrical activity. You're video taped so they can always look back and see what you do during a seizure. Then when I had it done at USC (University of Southern California), they also stopped all my meds cold turkey to try and make more seizures happen. Also to see what they worst seizure I'd have was. They can also do an invasive EEG. That's where they put some itty bitty openings into your scull to place the wires there incase they can hardly detect things just glued to the top of your head. but they have to get your permission to do that. The electrical activity in the brain moves so fast it can pass by several wires before it's detected. That's basically the main reason they do the invasive EEG. If it looks a little odd on your EEG they might ask you if it can be done. If you ever need more info., or need to talk by email. My address is shawn_wittman@att.net I hope it goes good for you.
Sincerely
