Figure 7

k-means clustering using FCOR values as voxel features in the thalamus

(A) Shows the mean silhouette value as a function of the number of clusters k. Arrows indicate the value of k with the highest and second highest silhouette values.

(B) Shows thalamic parcellation using k-means clustering with 2 and 3 clusters (k = 2 and 3) using FCOR values generated using resting state network templates in the Shirer and Gordon atlases. See also Figure S4.

(C) Shows the ratio of voxels within each parcel with strong (mean FCOR value >0.1) connections to different resting state networks in the Shirer and Gordon atlases. The left column shows the ratio for the 2-cluster parcellation while the right column shows the ratio for the 3-cluster parcellation. See also Figure S5.
