Edge-bundled DSI and resting-state connectivity

The image shows the result of the application of a method from the field of information visualization, force-directed edge-bundling, to two connectivity datasets. Both graphs (DSI-based on the left and resting-state based on the right) contain nearly 4000 single connections between 1015 regions of interest, which makes their visualization in anatomical 3D brain space a challenge. Edge-bundling groups together similar connections through the simulation of electrostatic attraction forces, and thus helps to make underlying structure visible.
