(A) Genotype based analysis of the BOLD response during the Time Discrimination Task. Contrast: 7-repeat absent > 7-repeat present. (B) Brain activation differences for the Time Discrimination Task in the cerebellum (x = −15, y = −48, z = −36). (C) Brain activation differences for the conjunction of both tasks (Incompatibility and Time Discrimination Task) in the middle frontal gyrus (x = −39, y = 39, z = 24, x = −36, y = 30, z = 9). Contrast: 7-repeat absent > 7-repeat present.
