Brain regions identified by the interaction term between age and stimulus valence. For hemisphere, R = right, L = left, M = medial. F = maximum F statistic for a given cluster. The correlation between age and each stimulus category is reported under the columns labeled “Avers r” and “Neut r” along with their statistical significance (*p < 0.05, **p < 0.01, ***p < 0.001). Subclusters that contained 20 or more voxels are reported under their supracluster.
