A statistical analysis comparing the percentage of BrdU-labeled cells in the subgranular zone plus inner third with the mid plus outer third of the granule cell layer reveals a slow redistribution away from the subgranular zone (see also Fig. 1C and Fig. 3). The upper half of the table gives the percentage of the BrdU-labeled cells in SGZ plus inner third of the GCL (Fig. 3). In the lower half, the P-values of the comparisons are listed. There is no indication of a continued migration towards the molecular layer. ANOVA (F=3.057): P=0.0199. Fisher post-hoc tests; significant P values are bold.
