Figure 4

AR and ERα expression in the MPOA only partly overlaps with ARO expression. Brightfield photomicrographs of autoradiograms and schematic drawings of coronal sections from a female breeder illustrating the expression pattern of AR, ERα and ARO in the medial preoptic area. Shown are adjacent sections from the same female brain of the left hemisphere at the level of the caudal end of the anterior commissure (A-C) and when the commissure has ended (E-G). Panels D and H show schematic overlays of the expression pattern of all three genes. Scale bar = 500 μm.
