Out-of-Body Experience on Demand

GT_Alias writes "CNN has an article reporting that some neurology researchers in Switzerland have triggered repeated out-of-body experiences by firing certain electrodes in the patient's brain. It seems that a part of the brain called the angular gyrus, responsible for logic and spatial awareness, triggers the sensation."

Here's an interesting discussion I had with my wife:

"What if stimulating that part of the brain causes *actual* out-of-body experiences rather than just the perception. What if you consciousness is disengaged from your body? How can the researchers tell the difference between *real* and *perceived* out-of-body? Did they ask the subjects to perform a task (such as observe something outside their field of view) that would only be possible in an *actual* out-of-body? Essentially they have proved an causal link between stimulation of this area of the brain and out-of-body experiences. They have not proved that the experience was perceived and not real."

Of course this doesn't mean it's real any more than it means it's just perception. Simply put, the experiement has only shown a causal link, without accurately examining the "effect" that follows the cause. Just because you can trigger it, doesn't mean it's fake. I would like to see them follow up with some tests of the "experience" to determine whether it is a perceptual recreation of the scene from different perspective.

Once they prove this, they will also have only proven that you can trigger "fake" out-of-body. That still does not prove that there is no "real" out-of-body that can occur under other circumstances.

By the way, I don't have any reason to believe in out-of-body being anything more than a perceptual issue, but the science here doesn't address that question.

> And what if, following a long philosophical tradition, the perception is in fact the actual reality? What if there is no actual world and all we have is our pont of view on them? There is something like this in Dostoievski's Karamazov, when he says that it doesn't matter if God exists or not, provided you can feel him. Nietszche also said that we build our reality in the same way when we are sleeping and when we are awake. I could quote many other writers and post-structuralists that deal with this problem in the same way, but [...]

...in the meantime, what if there was an actual reality? What if there was an actual world, and all we silly hairless apes had to go on is the evidence of our senses, and the ability of our intelligence to interpret the data passed back to us by our senses?

There's something like this in Schrodinger's and Einstein's and Pauli's theories, where you can't tell if the cat's alive or not, provided you don't observe it, and that matter and energy are interchangeable, and that electrons can't occupy any energy state they bloody feel like, but that they exist only in one of a finite number of discrete states at one time, and that you can make 'em jump from one state to another, but you can never shove 'em halfway in between these states.

> I know it is not a popular scientific tradition among americans and, specially, among computer scientists, but it is a pretty interesting line of thought.

I know it is not a popular poststructuralist tradition among academics, and, specifically, among philosophers, but the notion that there exists an objective reality, whose nature can be determined through the scientific method, is also a pretty interesting line of thought.

> It will sure be difficult to show he who had an out-of-body experience that what he saw is an illusion.

A lot of people tried the "objective reality" idea, built devices like transistors, cathode ray tubes, radio and X-ray telescopes, nuclear weapons, and laser keychain pointers based on those principles.

In the meantime, what have postmodernist and poststructuralist theorists brought us, other than graduate papers on postmodernism?

I think the scientist denying the OBE-believer's claim as mere illusion has a much easier time of it than a poststructuralist philosophy student's attempted denial of everything from the 15-kiloton explosion over Hiroshima and Nagasaki to the 0.5 milliwatt HeNe laser reflecting annoyingly off his computer's display after having been aimed there by a couple of wise-ass geeks in the engineering lab across campus.

I can't speak for Dostoevsky, but I think Nietzsche would have been embarassed at you. Who, since Nietzsche's day, has done more to completely redefine our understanding of reality than the scientist? Will to Power, indeed.
