Hear what the brain scanner sees. Data from functional magnetic resonance imaging (fMRI) are converted to musical sound. (This is the short version; See the 6-part "Music of the Hemispheres" for more.) Data are preprocessed into "independent components," regions of the brain which activate or deactivate in unison. Each component is assigned a tone, and the tone gets louder or softer in proportion to the degree of activity in the corresponding brain region. So, a melody is the moving center of metabolic energy, dancing all over the brain
