Modern science assumes that our consciousness is generated solely by electro-chemical processes in the brain, a fortunate byproduct of billions of neurons recording and processing sensory information as it comes in. But that view comes into question if one take into account stories from ancient traditions of astral travel, and more modern accounts of out-of-body experiences by individuals that live at the edge of reality as we know it.

However, researchers at the University of Wisconsin have made a step towards making consciousness a quantifiable phenomenon, where science may be able to address it in a more direct fashion.
