From: Mindfulness training induces structural connectome changes in insula networks
Overview of the connectome analysis for mindfulness training. (1) Connectomes are obtained from pre- and post-training data. Each entry in the connectome matrix contains connection strength for a given connection (e.g., insula to OFC), which is computed by dividing the raw number of tracks from tractography by the average volume of each pair of ROIs. (2) Three global graph-theoretical metrics were computed on the overall connectome: mean strength (B), global efficiency (E), and mean clustering coefficient (C). (3) Connection density (i.e. connection strength) was summed across left insula and right insula, yielding two summary metrics of left and right insula mean connection density.
