FIGURE 3.

Androgen receptor (AR) immunoreactivity (AR‐IR) in adult mouse brain. (A–H) Fluorescen images showing AR‐IR in the adult female mouse brain (postnatal day [PND] 56–70). AR‐IR was observed in almost all areas where we observed Ar mRNA. Selected areas from (A) cerebral cortex (dorsal and ventral anterior cingulate area, ACAd, ACAv), (B) hippocampal formation (pyramidal layer of fields CA1 and CA2), (C) cerebral nuclei (lateral septal nucleus, caudodorsal, LSc), (D) thalamus (paraventricular nucleus of the thalamus, PVT), (E) hypothalamus (subparaventricular zone, SBPV), (F) midbrain (periaqueductal gray, PAG), (G) pons/medulla (medial vestibular nucleus, MV) and (H) circumventricular organs (subfornical organ, SFO) are shown. AHN, anterior hypothalamic nucleus; alv, alveus; AQ, cerebral aqueduct; IG, induseum griseum; MS, medial septal nucleus; PRP, nucleus prepositus; PT, parataenial nucleus; 3V, third ventricle; 4V, fourth ventricle.
