Figure 6. Hippocampal neurogenesis.

Figure 6.

Assessment of estimated number of DCX positive cells (A) showed that long-term (Aged LT Ex), but not short-term (Aged ST Ex), exercise increased hippocampal neurogenesis relative to aged controls (Aged CON). As expected, aged mice in all groups had fewer DCX positive cells compared to young (Young CON) mice. There was no difference in the volume of the granular cell layer across groups (B). Representative images (C). Plots show the median number of DCX positive cells and the 25th and 75th quartiles by the box and the 5th and 95th percentile by the whiskers with individual data points shown as overlaid dots. Symbols indicate a significant difference from young control (*), aged control (^), or aged short-term exercise (+).
