Mean difference in z-score-converted correlations of mean ¹⁴C 2-DG uptake between biological odors (male odor, maternal odor) and the no odor control condition in three different network modules across age. A, PFC-Amygdala/hippocampus module. B, PFC-olfactory cortex module. C, Amygdala-hippocampus module. Groups with the same alphabetic label are not significantly different from each other based on post hoc tests (p < 0.01).
