Fig. 4.
Photomicrographs depicting BrdU-ir at 4 different rostrocaudal levels of the SCN at half-day intervals throughout the neurogenesis period for the SCN. Ventral BrdU-ir most prevalent in the early stages of neurogenesis (E10.0–10.5), while dorsal BrdU-ir is more prevalent in the later stages of neurogenesis (E11.5–12.0). Caudal BrdU-ir is more prevalent in the early stages of neurogenesis (E10.5), while rostral BrdU-ir is more prevalent in the later stages of neurogenesis (E11.5) (Scale bar = 100 μm).
