This video shows the white matter connections and grey matter activity of a real human brain measured on a 3 Tesla MR scanner, visualized in a special way: it unites in one three-dimensional view the functional and structural connectedness of the brain, and makes the brain activity of this individual subject audible by converting it into the background music to the video. By visualizing in this way both a diffusion tensor and resting-state functional MR dataset acquired using a 3 Tesla MRI scanner, this movie illustrates different concepts of image processing, connectivity and activity in a real human brain at rest. The background music was composed by assigning a musical instrument to the ten strongest functional patterns in the brain.
