Clusters above a threshold of Z > 3 are displayed with whole-brain correction for multiple comparisons (p < 0.01; n = 26). x, y, and z refer to the MNI coordinates corresponding to the left–right, anterior–posterior, and inferior–superior axes, respectively; Z refers to the highest Z-score within a cluster. A positive Z-value indicates a positive correlation between the subject's ratings and the BOLD response.
