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: people are subjected to a range of stimuli, ranging from a series of flashing lights to a driving simulator to, well, silence, while changes in brain activity are monitored by MRI. The results get passed through software that assigns specific tones to different regions of the brain, netting something like a song for each scan.Click to view


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.
