HD-FHN): 174 measurements, TR/TE = 2250/30ms, flip angle = 78°, GRAPPA acceleration factor = 2, slice thickness = 3.0mm with no inter-slice gap These minor acquisition differences, which were balanced across groups, were necessary given an upgrade to the Trio. Direct whole-brain voxel-wise testing of the two acquisitions showed no significant differences in BOLD activation to olfactory stimulation across all three odorant sets (p < 0.05, false discovery rate corrected).
