(a) Diagram showing timescale of treatments, (b–d) Cells immunoreactive for (b and c) BrdU and (d and e) Ki-67 in the dentate gyrus of the hippocampus. Adrenalectomy significantly increased proliferation of progenitors (§P < 0.0001) whilst raised corticosterone suppressed this process (†P < 0.0001), as shown by (f) BrdU and (g) Ki-67 cell counts.
