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).

Beethoven stretches out and relaxes. Gorillas belch to let others know where they are. Fish sing the body electric (.mov, 12 MB) for food and safety. How has your own perception shaped your worldview?

Researchers have found that prolonged concentration on a difficult task actually switches off a person's self awareness. Fancy experiencing this sensation for yourself? That would be an oxymoron in existence. Just lay back and let the orgasm take hold.

If the universe is a hologram and the healthy human brain a valve of consciousness then where'd this mental infinity come from? Are we simply living the simulacrum? Or does Pi protect us all, forever, infinitely?

How do we see? This site by Dr. Dale Purves makes it obvious we don't see things like a camera in any way. Check out the interactive demos, test your perceptual abilities, and read the research explaining why this happens. Number 12: Color Contrast Cube is particularly startling. Warning: Totally Flash interface, but appropriate for subject matter. More experiments at a less Flash-y associate's site.

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.

sandlot science ... optical illusions and visual oddities... hundreds of exhibits and interactive demonstrations.

A professor of vision science at MIT understands that life isn't just black and white, even though we often see it that way. This amazing illusion proves it, and these slick, fast-loading, Flash demonstrations of lightness perception show how it's done. (My favorite is the "Koffka Ring".) White paper here, for deeper background.
