The total number of GFP⁺ cells from the dentate gyrus is shown at indicated time points after viral injection. At 48 h, runners had a greater percentage of GFP⁺ cells labelled for Tuj1-β (P < 0.04) and NG2 (P < 0.05) than controls. At 4 weeks, the percentage of GFP⁺ cells co-labelling with neuronal markers was significantly higher in runners than in controls (NeuN, P < 0.01; calbindin, P < 0.01; Tuj1-β, P < 0.04). All data are presented as means, with s.e.m. in parentheses. Asterisk, P < 0.05; double asterisk, P < 0.01.
