Fig. 4.

Overlay lesion plots of the subjects with high re-cancellation rate (a) and low re-cancellation rate (b). The number of overlapping lesions is illustrated by different colours coding increasing frequencies from blue (1 patient) to orange (all 5 patients). c Contrast maps subtracting superimposed lesions of patients in each subgroup. The number of patients demonstrating brain damage in a specific location after subtraction of the other subgroup is illustrated by different colour coding (in blue shades for lesions specific to the low re-cancellation subgroup and in yellow shades for lesions specific to the high re-cancellation subgroup, with magenta representing areas with equal lesion frequency in the two subgroups)
