Long‐term neuronal survival. A similar number of E19‐born cells were present at 2 and 6 months of age (T ₁₅ = 0.008, p = .99). There was a 15% loss of P6‐born cells between 2 and 6 months of age (T ₃₀ = 2.5, *p = .02). A similar number of P21‐born cells were present at 2 and 6 months of age (T ₂₉ = 1.1, p = .3). Note the 10× smaller y‐axis scale for the P21 data. Bars represent mean ± SE
