“Henrik's work speaks to the idea that there is no such thing as a soul or a self that's independent of the brain.”

Out-of-body experience: Master of illusion: Out-of-body experiences are just part of Ehrsson's repertoire. He has convinced people that they have swapped bodies with another person, gained a third arm, shrunk to the size of a doll or grown to giant proportions. [ . . . ] But Ehrsson's unorthodox apparatus amount to more than cheap trickery. They are part of his quest to understand how people come to experience a sense of self, located within their own bodies. The feeling of body ownership is so ingrained that few people ever think about it — and those scientists and philosophers who do have assumed that it was unassailable. [ . . . ] Ehrsson's work also intrigues neuroscientists and philosophers because it turns a slippery, metaphysical construct — the self — into something that scientists can dissect.

World's Oldest Optical Illusion Found?

World's Oldest Optical Illusion Found? A 15,000 year old piece of an atlatl (spear chucker) shows definite signs of being a Gestalt shift optical illusion (as demonstrated here, here, and in the classic duck/rabbit picture). Although not as well defined as modern optical illusions (like the really tripped out Neave Strobe), it likely demonstrates a stage of cognitive awareness in human psychological development.

Video Ergo Sum

Virtual Out-of-Body Experience. Using two procedures to deliberately scramble a person's visual and tactile senses, neuroscientists are able to induce "out-of-body" experiences in people. The effect is the same as the 'rubber hand illusion', but extends the effect to the whole body instead of just one limb (you can try the hand illusion for yourself).

Brain tricks

Red and green dots have never been so interesting. At least to a geek like me. I love it when my brain plays tricks on me.
