Correlation matrices representing the difference of ratios of mean ¹⁴C 2-DG uptake between each biological odor (male odor, maternal odor) and the no odor condition (bivariate correlation matrix for each odor − bivariate correlation matrix for no odor) at PN7, PN14, and PN23. Changes in functional connectivity across odors and ages can be observed in specific neural network modules. Core olfactory areas are shown in purple and red, amygdala areas in blue, hippocampus subareas in black, and orbitofrontal and PCX areas in green. ACC, Anterior cingulate cortex; IL, infralimbic cortex; PL, prelimbic cortex.
