    Soundtrack Of The Human Brain Revealed By Remixed Brain Waves

    Scientists have combined and translated two kinds of brain wave recordings into music, transforming one recording (EEG) to create the pitch and duration of a note, and the other (fMRI) to control the intensity of the music. The research, published in the open access journal PLOS ONE by Jing Lu...
