Notes: L, left; R, right; Location, coordinates are for the maximum z-stat in MNI152 2009a symmetrical space. Brain activation during incongruent vs congruent trials (I-C contrast) in negative ACM and positive ACM was each contrasted by neutral ACM. An individual-voxel threshold z value of 2.05 was used for all masks except for NAc.

^aNAc was thresholded with z = 1.96.
