Figure 5. Counts of proliferating and newborn cells in the pyriform cortex.

Oligodendrocyte turnover in the cerebral cortex was quantified in pyriform cortex (shaded area above) as defined in the text. The density of BrdU⁺ cells, shown for GH/IGF-I replete (open bars) and deficient rats (filled bars) in the Proliferation and Survival groups, was similar at the two time points and did not differ between GH/IGF-I deficient and replete rats. All values mean±sd.
