Results of support vector regression lesion-symptom mapping (SVR-LSM) after voxels thresholded at P < 0.005 underwent cluster-level corrections with 10,000 permutations (cluster threshold = P < 0.05). 3-Dimensional models of resulting clusters were generated using the Montreal Neurological Institute template via BrainNet Viewer (https://www.nitrc.org/projects/bnv/). a Lesions in a cluster of 8,333 voxels in the left lateral PFC were predictive of impaired picture naming (P = 0.045). b Lesions in a larger cluster of 21,512 were voxels predictive of impaired auditory naming (P = 0.0034). Clusters in a and b overlap completely with the cluster in a extending deeper into subcortical regions. c Results of SVR-LSM using the principal component scores for each participant on the first principal component (PC1). This cluster consists of 11,944 voxels (P = 0.019) and demonstrates overlap with the clusters in a and b.
