The number of asymmetric spine synapses in layer II/III of the mPFC (upper panel) as well as the stratum radiatum of the CA1 hippocampal area (lower panel) in castrated male rats after treatments with sesame oil vehicle (OIL/OIL), TP (OIL/TP), bisphenol A (BPA/OIL), and bisphenol A + TP (BPA/TP). The labeling of columns corresponds with the group names in Materials and Methods section. The asterisks indicate that the OIL/TP group is significantly different from all other treatment groups (Tukey’s test, P < 0.001).
