Listening to your brain

From the New Scientist:
What does the human brain sound like? Now you can find out thanks to a technique for turning its flickering activity into music. Listening to scans may also give new insights into the differences and similarities between normal and dysfunctional brains.

Brain scans created using functional MRI consist of a series of images in which different areas light up with varying intensity at different times. These can be used to determine which parts of the brain are active during a particular task.
