Connectograms and Circos Visualization Tool

Connectograms are circular representations introduced by LONI researchers in their NeuroImage article “Circular representation of human cortical networks for subject and population-level connectomic visualization:

“This article introduces an innovative framework for the depiction of human connectomics by employing a circular visualization method which is highly suitable to the exploration of central nervous system architecture. This type of representation, which we name a ‘connectogram’, has the capability of classifying neuroconnectivity relationships intuitively and elegantly.”

Details of the graphic are explained in the PLoS article. The outermost ring shows the various brain regions by lobe (fr – frontal, ins – insula etc.). The left (right) half of the connectogram figure represents the left (right) hemisphere of the brain and the brain stem is at the bottom, 6 o’clock position of the graph.

Based upon this geospatial model of the damaged brain overlaid against the typical brain connectogram from the healthy population they created another connectogram indicating the connections between brain regions lost or damaged in the accident.
