Figure 6. Comparison of the numbers of doublecortin-positive (DCX+) newly born neurons between intact middle-aged rats (n = 5) and middle-aged rats (n = 5) that underwent acute seizure (AS) activity in the subgranular zone-granule cell layer (SGZ-GCL; A1), the dentate hilus (DH; B1), the SGZ-GCL + DH (C1).

The numbers of newly born neurons are proportionately increased after AS activity in the SGZ-GCL (A1) and the DH (B1). The bar chart in D1 compares percentages of DCX+ neurons that are located in the DH between the two groups. Note that, the percentage of DCX+ neurons that migrate into the DH are comparable between intact middle-aged rats and middle-aged rats that underwent AS activity.
