Figure 4.

Striatal activation associated with the reduction of perceptual uncertainty. The colored regions were more active when the second picture in a trial reduced the perceptual uncertainty induced by the preceding picture (i.e., the second picture in the B–C_{corresponding} condition) than when the second picture did not reduce the perceptual uncertainty induced by the preceding picture (i.e., the second picture in the B–C_unrelated condition). R, right; L, left. The displayed activations are the cluster-corrected Z statistic maps (p < 0.05) from the striatal ROI analysis, which were overlaid onto the standard MNI brain.
