I read this article in the Economist about the discovery of the brain region that is responsible for creating the "out-of-body" experience and how now these experiences
can be induced on volunteers in the lab. I think this is really cool because I've always been very curious about these "out-of-body" experience when I learn meditation. So basically these studies are suggesting that if you can control the brain (through meditation or other means), you will be able to create these experience at will.
Now we just need some scientific explanations for those out-of-body experience that people travel to places that they have never been to before but can accurately describe all the details upon return to body.
