Brain music

Sleep researchers in Toronto turn brainwaves into "music", which, when listens to by the person whose brainwaves were used, induces sleep. They believe that they can use similar techniques to induce other states. It sounds like it works on a similar principle to "brainwave machines", only customised to the individual brainwaves of the user.
"Even the diseased brain has such enormous reserves that we can use the brain activity, even from a diseased brain, to heal it," he says. An anti-anxiety response, for example, can be produced even in someone who is seriously impaired by reproducing sounds that stimulate relaxation.
