Treatment difference for novel metaphorical compliments based on cycle contrasts (fertile > luteal) in activated brain regions: left MFG, dACC, pMCC (n = 62). (A) The t map of the post hoc independent t-test effect showed three activated clusters peaking at the left MFG (x = –30, y = 32, z = 26; t₆₀ = 5.13), dACC (x = 9, y = –28, z = 29; t₆₀ = 4), and pMCC (x = 24, y = 26, z = 26; t₆₀ = 4.39). Parameter estimates were extracted using the peak MNI coordinates. (B) Extraction based on the fertile > luteal contrast revealed that oxytocin significantly increased activation in the identified regions relative to placebo, *p < 0.05, ^**p < 0.01, two-tailed t-test. Bars indicate M ± SE. L, left; R, right; MFG, middle frontal gyrus; dACC, dorsal anterior cingulate cortex; pMCC, posterior middle cingulate cortex.
