O-Q Quantification of neurogenic (Ngn1+) RGs and BPs (O), newborn BPs (P) or expanding (Tbr2-Ngn1-) RGs (Q) in control cortices after exposure of the pregnant dams to 21% O2 or 80% O2 (mean±SEM; N=5; ** p&lt;0.01). Full, dotted and dashed lines indicate basal and apical boundaries of the cortex or boundaries of the cortical zones, respectively.
