fMRI data analysis
Amygdalar and hippocampal functional resting-state connectivity was probed in a whole brain seed-to-voxel analysis. To assess the connectivity of the amygdala and hippocampus, seed-to-voxel connectivity maps were estimated for each participant using CONN. The seeds (left and right hippocampus and left and right amygdala) were anatomically defined using the aal atlas in the Wake Forest University PickAtlas, version 3.0. Statistical analyses were conducted using CONN. Connectivity maps for each of the seeds were compared using analyses of variance (ANOVAs) with the between-subjects variables “nasal spray treatment” (PLC
