White matter correlates of Analysis 2 — object naming after controlling for other language tasks and Analysis 3b — a ‘unique’ naming component. Age, gender, years of education, stroke–scan interval, stroke–screen interval and general cognitive state indices (orientation scores) were entered as covariates in both analyses.

Note: the first column under each analysis reports the size (number of voxels) of each of the clusters with amplitude of voxels surviving Z = 2.32 (uncorrected). In each cluster, the MNI coordinates (x, y, z) and the peak reliability in brackets (Z) are reported. Acronyms: AF — arcuate fasciculus; MCP — middle cerebellar peduncle.
