This was a really FANTASTIC talk at TED about how your brain can learn to interpret new senses.

If you like tech stuff and psychology, then grab a cup of coffee or tea (if British) and enjoy this talk.

 As humans, we can perceive less than a ten-trillionth of all light waves. “Our experience of reality,” says neuroscientist David Eagleman, “is constrained by our biology.” He wants to change that. His research into our brain processes has led him to create new interfaces — such as a sensory vest — to take in previously unseen information about the world around us.
