Martijn D. Steenwijk’s video was a winner in the category of Best Video Illustration of the Brain in the 2012 Brain Art Competition 2012, run by The Neuro Bureau.

Martijn’s description of ‘The Brain at Rest’ video:

“By visualizing both diffusion tensor and resting-state functional MR data, this movie illustrates different concepts of image processing, connectivity and activity in a real human brain at rest. Background music was composed by assigning a musical instrument to the ten strongest functional patterns in the brain. The intensities of these patterns vary over time while the person is at rest in the scanner – these are “spontaneous” brain fluctuations that receive much attention in fMRI research now. By linking the intensity of each pattern to the pitch of its respective instrument a melody is generated, thereby making brain activity audible. The first part of the movie illustrates the source of the melody by showing functional patterns and their varying strengths. The second part shows the major fiber bundles which were obtained by running deterministic tractography from atlas seeds. In the third part, the seeds were replaced by spherical objects ‘running’ around the cortical surface. The last part combines structural connectivity with functional connectivity. Here, functional connectivity is visualized using volume rendering of the voxelwise functional correlation matrix. Together with its structural counterpart, this last part illustrates that structural and functional connectivity are quite different”.
