Abstract

Functional connectivity, a flourishing new area of research in human neuroscience, carries a substantial challenge for visualization: while the end-points of connectivity are known, the precise path is not. Although a large body of work already exists on the visualization of anatomical connectivity, the functional counterpart lacks similar methods. In order to optimize the clarity of whole-brain and complex connectivity patterns in 3D brain space, we develop mean-shift edge bundling, which reveals the multitude of connections as derived from correlations in brain activity of cortical regions.
