Regions of Interest (ROI) analysis of relative 2-DG uptake in response to maternal odor, acetophenone, and no odor presentations in prefrontal cortex (PFC) areas of the anterior cingulate cortex (ACC; A), medial prefrontal cortex (mPFC; B), and basolateral amygdala (BLA; C) of pups at postnatal day (PN)7, PN14, and PN23. Bars represent the mean level of 2-DG uptake (±S.E.M.) in the three ROI. Significance indicated by *, with ** used to indicate the two odors are significantly different from one another. A total of 73 pups were used, with N = 7–9/group.
