((( M ))) Once again -- I'm far from being an expert but I THINK this is a very advanced VEEG where the electrodes NEED to touch the actual covering of the brain instead of just the skin on the skull.
I was told that this would be necessary for me if the usual VEEG did not produce the necessary results. Thank God!
I did not know that this caused pain. Oh, that's terrible.
Other people, smarter and more informed that I, will be along very soon.... hang on.
