Figure 3.

Activation of the septal/preoptic-anterior hypothalamic and medial FPC, predicted a priori, as well as in the left posterior superior temporal sulcus region (data not shown) and precuneus (Prec), observed in the affiliative versus nonaffiliative contrast. To provide a better visualization of the spatial extent of the significantly activated clusters, statistical maps are displayed at uncorrected p = 0.005, minimum cluster size = 5 voxels. These clusters survived FWE correction for multiple comparisons (p < 0.05) either at the whole-brain level or over an a priori anatomical region of interest (Table 2; additional clusters showing in this map did not survive FWE correction). Activation results overlaid on a segmented and inflated brain template are shown at the right inferior quadrant.
