Structural Angle and Power Images Reveal Interrelated Gray and White Matter Abnormalities in Schizophrenia

Table 4

White matter labels for networks detected by SBM. Voxels above a threshold of |𝑍|>3.0 were converted from Montreal Neurological Institute (MNI) coordinates to the ICBM DTI-81 coordinates and entered into a database to assign anatomic labels. The volume of significant white matter voxels within each fiber tract area is provided in cubic centimeters (cc). The areas with volume above 0.1 are listed. The percentage of the fiber tract containing significant white matter voxels is also provided. Within each fiber tract, the maximum 𝑍 value and its coordinate are provided.
