Structural analysis of task fMRI t-maps, obtained using local structure tensor analysis (Knutsson, 1989) where the eigenvalues of the structure tensor denote the amount of spatial structure. (a) Quantification of the amount of anisotropic structure observed in t-maps, specified by the mean structure map value, averaged across the task’s experimental conditions. (b) Correlation between subjects’ QA maps and structure maps, averaged across each task’s experimental conditions. Markers shows the median value across the 95 subjects.
