Distribution of ESR2⁺ cells in mouse and rat mesencephalons and cerebral cortexes. Representative photomicrographs of ESR2- and Nissl-stained brain sections containing the DRN of mice (A) and rats (C) and the cerebral cortex of rats (D). The dashed line in panel A indicates the region of interest. The right images of panel D correspond to magnified views of regions indicated by the small frames. Aq, mesencephalic aqueduct; mlf, medial longitudinal fasciculus; opt, optic tract; st, stria terminalis. Scale bars = 100 µm. The numbers of ESR2⁺ cells in the DRN of mice (B). Data are presented as the mean ± standard error of the mean (n = 4). Black dots represent individual data
