Results of mapping tool-processing behavior with self-obtained WM tracts. A, Schematic of the self-obtained WM tracts associated with tool use and/or tool conceptual processing. The correlations of WM tract integrity with tool use or tool conceptual performance are shown in B and C, respectively. Row 1 shows the shape of the tracts. Rows 2 and 3 show the correlograms of lesion analysis and FA analysis, respectively. The y-axis in the correlograms indicates the residual of the lesion volume (Lesion index) or mean FA value (FA index) with patients' total lesion volume regressed out. Full names of the seeds are listed in Table 1.
