A professor at Trinity College in Connecticut has written what is essentially a MIDI player for the human brain, converting MRI imagery into a sort of bleeping, blooping ambient music.
Here's how it works: subjects were given a variety of stimuli, ranging from a series of flashing lights and a driving simulator to just sitting still in silence, while changes in brain activity were monitored by MRI. The results were then passed through software that assigns specific tones to different regions of the brain, netting something like a song for each scan.
These impulses aren't inherently musical—they've been deliberative assigned tones that sound nice together, and even so sound rather chaotic—nor would you expect them to be, since this is just a novel way to present MRI. What's fascinating is how noticeably different the sounds of active and dormant brains, or troubled and untroubled brains actually are. And not to diminish the seriousness of schizophrenia in any way, but the scanned map and accompanying sounds for an affected brain, seen at about 40 seconds into the video, are nothing short of awesome.
