Timecourses of regions showing a main effect. A: Left inferior parietal lobe, MNI coordinates X = 34, Y = –56, Z = 44. This region was positively activated in the block-design comparison, as a result of a hemodynamic transient peaking at about 6 s. Error bars represent standard error of the mean across subjects. B: Right inferior parietal lobe, (coords. 33, –60, 44), also positively activated. C: Ventral anterior cingulate cortex, (coords. 0, 43, 1), deactivated on the block level because of a later negative transient peaking at about 10 s. D: Posterior cingulate, (coords. 0, –36, 40), also deactivated due to a late transient. E: Left hippocampus, (coords. –32, –25, –16), deactivated. F: Right hippocampus (coords. 28, –29, –18), deactivated.
