"Blanke found that electrically stimulating one brain region — the right angular gyrus — repeatedly triggers out-of-body experiences. Blanke and his team were using electrodes to excite the brain of a woman being treated for epilepsy. The right angular gyrus integrates visual information — the sight of your body — and information that creates the mind's representation of your body. This is based on balance and feedback from your limbs about their position in space. 'It makes perfect sense,' agrees Peter Brugger of University Hospital, Zurich, in Switzerland, who studies the phenomenon. 'We have representations of our entire body that can be dissociated from our real body,' he says. But this is an isolated case, he points out."
Electrodes trigger out-of-body experience, Nature, 19 September 2002

--Son, been wondering about this, ah, "screwing in" you kids are doing. This matter of the, shooting electricity into head, ha ha?

--Waves, Pop. Not just raw electricity. That's fer drips!

--Yes, ah, waves. "Keying waves," right? ha-hah. Uh, tell me, son, what's it like? You know I've been something of a doper all m'life, a-and-

--Oh pop. Cripes. It isn't like dope at all.

--Well we got off on some pretty good "vacations" we called them, some pretty "weird" areas they got us into's a matter of fact-

--But you always came back, didn't you?

--What?

--I mean, it was always understood that this would still be here when you got back, just the same, exactly the same, right?

--Well ha-ha guess that's why we called 'em vacations, son! Cause you always do come back to old Realityland, don't you?

--You always did.

--Listen Tyrone, you don't know how dangerous that stuff is. Suppose someday you just plug in and go away and never come back. Eh?

--Ho, ho! Don't I wish! What do you think every electrofreak dreams about? You're such an old fuddy duddy! A-and who sez it's a dream, huh? M-maybe it exists. Maybe there is a Machine to take us away, take us completely, suck us out through the electrodes out of the skull 'n' into the Machine and live there forever with all the other souls it's got stored there. It could decide who it would suck out, a-and when. Dope never gave you immortality. You hadda come back, every time, into a dying hunk of smelly meat! But We can live forever, in a clean, honest, purified, Electroworld--

--Shit, that's what I get, havin' a double virgo for a son...
