Expression pattern of AR, ERα and ARO mRNA in forebrain regions of breeding female Damaraland mole-rats. Brightfield photomicrographs of autoradiograms of coronal sections through the mole-rat brain illustrating the distribution of AR, ERα and ARO mRNA visualized by in situ hybridization. Panels A, C and E illustrate adjacent sections from the brain of a female breeder at the level of the preoptic area (comparable to Bregma 0.22 of the naked mole-rat brain atlas . Panels B, D and F come from sections of the same female brain at the level of the caudal hypothalamus, (comparable to Bregma −0.69 mm of the naked mole-rat brain atlas .
