40 Supplementary materials Supplementary Figure 2. SVR-LSM results for the RAVLT direct recall for both groups combined when etiology was added as covariate. Panel A shows the lesion overlap for this task when lesions from both groups are combined. The color bar indicates the number of patients with overlapping lesions. Panel B shows the voxels that were significantly associated with worse performance (yellow). The yellow color indicates the p-value for each voxel. Delayed recall verbal memory (Supplementary Figure 3) In the combined SVR-LSM analysis, lesions in the left ILF (most voxels with peak significance; 26.2%), optic radiation (29.2%), posterior segment (14.7%) and IFOF (12.3%) were strongly associated with task performance. Significant voxels extended into grey matter areas, including the left hippocampus (39.2%), parahippocampal gyrus (18.1 %), inferior temporal gyrus (12.3%). Significant areas largely overlapped with the areas found when the analysis was run for the tumor and stroke group separately (Supplementary Figure 3 and Supplementary Table 5). However, while lesions in the left putamen were highly associated with worse task performance in the stroke group, this area was not significant in the combined group SVR-LSM analysis. A
