Brain network eigenmodes provide a robust and compact representation of the structural connectome in health and disease
Fig 2
A white matter voxel’s importance for a given eigenmode is defined as the decrease in the corresponding eigenvalue when a 12mm-diameter lesion is placed at that voxel, damaging encompassed connections proportionally to the edge volume removed.
These importance maps were averaged from the MNI152 1mm-registered maps of ten healthy adults, two scans each. The brighter the voxel, the larger the corresponding decrease in eigenvalue. The X and Z coordinates of each taken axial and sagittal plane are shown for reference: increasing X denotes the sagittal plane moving from the right to left side of the brain, while increasing Z denote inferior to superior axial planes.
