Quantification of receptor autoradiography for OXTR in C57BL/6J mice demonstrates transient developmental profiles. OXTR binding with highly selective OXTR ligand is evident in (A) the CA3 of the dorsal hippocampus, (B) the septum, and (C) the neocortex sampled at S1. For all three brain regions, there was a main effect of age. In the septum and the hippocampus, this was driven by the difference in binding between P0 and P14–P21. In the neocortex, the main effect of age was stronger and driven substantially by the peak at P14. *p < 0.05.
