Figure 1.
The two cluster result found the A) task-negative and B) task-positive systems.
Figure 2.
The cluster dispersion metric (Equation 4) for different numbers of clusters.
Cluster dispersion was minimized for seven, eleven, and seventeen clusters.
Figure 3.
A) DMN, B) FPC network, C) LAN network, D) VAN, E) SMN, F) VIS network, and G) DAN. The right hemisphere is displayed for the VAN because it was right lateralized.
Figure 4.
Subcortical involvement of the seven cluster result.
Axial slices are shown in radiologic convention. A) DMN, B) FPC network, C) LAN network, D) VAN, E) SMN, F) VIS network, and G) DAN.
Figure 5.
Temporal inner products (Equation 6) between centroids from the A) seven cluster result and B) eleven cluster result.
Figure 6.
The degree of uncertainty (Equation 7) as shown by the geometric mean of weights for each voxel in the A) seven cluster result and B) eleven cluster result.
Table 1.
Similarity measures for clustering results of the second study group compared to the first.
Figure 7.
Some RSNs from the A) seven cluster result were subdivided in the B) eleven cluster result.
The right hemisphere is displayed for the VAN and its subdivisions because they were right lateralized.
Figure 8.
In the eleven cluster solution, the LAN network and VAN were divided into approximately cortical and subcortical clusters.
Axial slices are shown in radiological convention of A) LAN1, B) LAN2, C) VAN1, D) VAN2.
Figure 9.
The relationships between the seven and eleven cluster results and the task-negative (TN) and task-positive (TP) systems from the two cluster result.
The A) spatial (Equation 5) and B) temporal (Equation 6) inner products between the two cluster and seven cluster results. The C) spatial (Equation 5) and D) temporal (Equation 6) inner products between the two cluster and eleven cluster results.
