from nytimes:

When people gaze at an illusory image of themselves through the goggles and are prodded in just the right way with the stick, they feel as if they have left their bodies.

The research reveals that “the sense of having a body, of being in a bodily self,” is actually constructed from multiple sensory streams, said Matthew Botvinick, an assistant professor of neuroscience at Princeton University, an expert on body and mind who was not involved in the experiments.

Usually these sensory streams, which include vision, touch, balance and the sense of where one’s body is positioned in space, work together seamlessly, Prof. Botvinick said. But when the information coming from the sensory sources does not match up, when they are thrown out of synchrony, the sense of being embodied as a whole comes apart.

The brain, which abhors ambiguity, then forces a decision that can, as the new experiments show, involve the sense of being in a different body.

i wonder what effect more research into this area will have on religious claims of out-of-body experiences. hopefully this is a step towards better understanding of mind-body experience, as well as larger metaphysical questions.
