Ambulatory E.E.G.

Today I got hooked up for an Ambulatory E.E.G. test. They take a pretty serious glue/iron-hard-epoxy-stuff and attach your standard set of electrodes to the top of your head. The leads are attached to a small WalkMan sized recorder. It runs on a couple AA batteries and contains a micro-drive that records up to 72 hours worth of electrical activty coming off the top (or the sides) of your head. I will be wearing this for the next few days...
