Female sexual behavior increases the number of c-Fos neurons in CaMKIIα neurons in the mPFC. (A) A histological image illustrating the double labeling for c-Fos and CaMKIIα. Arrows point to several double labeled cells in which nuclear staining for c-Fos is a black reaction product and cytoplasmic CaMKIIα is brown. (B) There were no differences in the total numbers of CaMKIIα labeled neurons in the total mPFC following sex behavior. (C) Sex behavior increased the number of c-Fos cells within CaMKIIα neurons for the total mPFC, demonstrating increased activation of PFC glutamatergic neurons following a single sexual experience (*indicates p < 0.01).
