XYZ in Talairach space indicate peak voxel coordinates. BA: Brodmann area. Pound signs (#) indicate other brain regions within the same significant clusters where peak voxels are located. Post-hoc comparisons are shown at peak voxels compared to baseline (**p < .01). T-scores column presents t-scores results from paired t-tests comparing cond/task (condition/task) 1 to cond/task 2 to explore the direction of F effects (*p < .05); positive values represent cond/task 1 > 2 and negative values represent cond/task 2 > 1. SC/MC/OA: single car/multiple car/object animal tasks.
