Most of us have heard of an out-of-body experience - the idea that a person's consciousness can travel and exist outside the physical body. Some of you may have even had such an experience. Now, researchers from the Karolinska Institutet in Sweden reveal how they induced an out-of-body illusion in healthy study participants.

Perceived self-location decoded from brain activity in temporal and parietal lobes
For their study, 15 healthy participants were placed inside a brain scanner while wearing a head-mounted display, on which the participants were able to view themselves inside the brain scanner from another area in the room.

The head-mounted display then showed each participant the body of a stranger standing in front of their body in the brain scanner. To trigger an out-of-body illusion, a researcher touched the participant's actual body with an object, while the display showed the stranger receiving identical touches in synchrony.

"In a matter of seconds, the brain merges the sensation of touch and visual input from the new perspective, resulting in the illusion of owning the stranger's body and being located in that body's position in the room, outside the participant's physical body," explains Guterstam.

The researchers then used this out-of-body illusion to "teleport" the participants to different locations in the room while monitoring their brain activity via pattern recognition techniques.

From this, the researchers found they were able to interpret participants' perceived location from specific activity patterns that occurred in the temporal and parietal lobes of the brain.

What is more, the team detected a link between the information present in these activity patterns and the extent to which participants felt their out-of-body illusion was real.

While this gives some really interesting insights into the human brain, I suspect the first application will be internet porn.

They could have achieved those results with LSD.

Oh, I think those results are fascinating. If other labs can repeat it it will change what we think of as consciousness.

Yep. Its not magical, its just the brain. The brain can do weird things, especially if its on drugs or low on oxygen.

I had one once while swimming underwater at a pool (trying to swim 115' underwater, in 1 breath, as a child).

Vision went to tunnels (dark rings with points of light), everything seemed quiet, I felt perfectly comfortably warm. It was the most peaceful experience in my life. Had a clear image of my grandmother, over on the side of the pool, reading her book (which she was doing, which I knew, since that is what she always did when she took us to the pool).

I remember thinking "if I died right now, I don't think I'd care".

If I die in a manner which I experience that, then it won't be bad.

I remember reading about a surgeon who kept hearing stories from his patients about out of body experiences. They would describe them in great detail. So, he took a number of objects (like pieces of paper with large numbers written on them) and hid them around the OR in the areas where the patients were describing, but outside of the view of the patients. Not a single person ever mentioned them.

ETA

Also, do you have a link to these stories? I'd like to read them.

Just because something can be artificially stimulated does not mean it cannot actually happen.
Maybe with the right artificial stimulation you could experience driving a car in your mind.
That would not disprove the fact that you can actual drive a car.

I can remember being a small child going in for dental work. The anesthesia made me feel and completely believe that I was floating and bumping into the ceiling. I knew without a doubt that I could fly if the ceiling wasn't there. I believe the dentist may have overdosed me somewhat.

That was a sensation I will never forget.

Yeah, but both of those mean dealing with a sketchy dude who watches cartoons waay to much and wants to talk to you about being "awake" and "universal conciousness".

This is done cleanly, in a lab.

Some people believe their dreams of floating around are actually real and they're a spirit flying around out of their body.

Thanks for the link, I've read that before but I went ahead and reread the entire thing. What he doesn't account for are these things. The brain being flooded with DMT before neural activity ends which causes many of these experiences (they've been reproduced, there are several good books about the...somewhat... unethical studies done). That could account, I say could because more study is needed, for the patients sense memories before they go below the critical threshold (which is retarded by environmental factors such as cold). It could also account for the similar experiences across cultures.

Here is where he goes off the rails in my opinion though:

Wired: Couldn’t the experiences just reflect some extremely subtle type of brain activity?

Parnia: When you die, there’s no blood flow going into your brain. If it goes below a certain level, you can’t have electrical activity. It takes a lot of imagination to think there’s somehow a hidden area of your brain that comes into action when everything else isn’t working.

These observations raise a question about our current concept of how brain and mind interact. The historical idea is that electrochemical processes in the brain lead to consciousness. That may no longer be correct, because we can demonstrate that those processes don’t go on after death.

There may be something in the brain we haven’t discovered that accounts for consciousness, or it may be that consciousness is a separate entity from the brain.



He says that AFTER he just said earlier in the article that death is a process. If it's a process then there's no supernatural explanation needed, although more study needs to be done. If it's just, "click done" as he alludes to later (when he starts to get a little philosophical) then how are those memories encoded into the areas of the brain that can be looked at when being recalled in an fMRI?

Then here:

Parnia: At the very least, it tells us that there’s this unique experience that humans have when they go through death. It’s universal. It’s described by children as young as three. And it tells us that we should not be afraid of death.


he basically lets his personal feelings totally eclipse his professional judgement.

This part:

Parnia: All the evidence we have shows an association between certain parts of the brain and certain mental processes. But it’s a chicken and egg question: Does cellular activity produce the mind, or does the mind produce cellular activity?


Is equally laughable and is begging to be smacked down as things like AI come online.

I had one during my coma after that unfortunate day outside Kandahar. I watched from above them as the Code team tried to start my heart back up, then everything went gray and I saw and spoke to relatives who passed before me. One particular relative had just passed while I was in the coma, there was no way I could've known that and "imagined" it.

After all of that, and actually hearing angels sing, then surviving with no permanent brain or lung damage...well, it's safe to say that I'm a firm believer these days in a higher power and that there really is something beyond death.
