Group-level gray matter mean intra-subject emotion perception encodings²⁴ of normative affect properties. Color gradations indicate the group-level mean encoding parameter (red indicating positive valence or high arousal, blue indicating negative valence or low arousal). Only group-level significant parameters (p < 0.05, global permutation test²⁷) are depicted (see Materials and Methods: Neuroanatomical Encoding Parameter Significance via Permutation Testing). Image slices are presented in Talairach coordinate space and neurological convention. Maximum mean voxel intensity |μ(z)| = 2.0. Only those clusters having 10 or greater contiguous voxels (NN = 1) are plotted.
