An fMRI scan of a subject looking at a simple visual stimulus appears here as music merged with a whole-brain visualization. Regions that are active get brighter, and their melody rises, as brain activity increases. At first, the video displays the visual cortex, which is nicely coupled to the checkerboard stimulus the subject was watching. But as more regions of the brain are added to the display, the visual activity is finally heard in a rich context of all-over brain activity. (less info)
