Supplementary Results
Network neuroscience often relies on the use of pre-existing parcellations to define the boundaries of the brain regions that will be submitted for network assignment and subsequent analysis. We present preliminary results that indicate that the topography of network partitions varies with the number of regions included in the parcellation when the parcellation algorithm is kept constant. This may be due to implicit assumptions in network assignment methods that lose important information about the multi-network connections of many regions, especially those showing “hub-like” properties. We argue that network neuroscience will need to move toward new methods that capture this information in order to gain a full understanding of the relationship between regional processes and network communication structure.
