Concurrent white matter bundles and grey matter networks using independent component analysis

Jonathan O'Muircheartaigh, Saad Jbabdi
2018 NeuroImage  
Here we apply independent component analysis to whole-brain tractography data to automatically extract brain networks based on their associated white matter pathways.  ...  This method decomposes the tractography data into components that consist of paired grey matter 'nodes' and white matter 'edges', and automatically separates major white matter bundles, including known  ...  In connectivity analyses (functional or structural), the choice of seed regions/nodes is critical.  ...
