Ar mRNA hybridization signal expression in male and female prepubertal and adult brain. Images from scanned autoradiographic film of adult, postnatal day [PND] 56–70 (A), and prepubertal, PND 12 (B) and PND 21 (C), male and female mouse brain. Select coronal sections are shown in rostral to caudal order. Darker signal indicates higher expression of Ar mRNA. Approximate distance from bregma (left column) derived from adult mouse brain (Paxinos and Franklin atlas). Scale bar = 4000 µm
