Figure 2

Representative images and quantitative analysis of the dendritic arborization of Golgi-impregnated neurons from the exercise (EX) and control (CTL) groups at 0 (P60), 30 (P90) and 60 (P120) days after the last exercise session (n = 5–6 in each age and group). Number of dendrites, dendritic nodes and ends, and total dendritic length were measured in the cortical neurons of layers and hippocampal neurons of the CA1 subfield (n = 10 neurons/region per rat). Dendritic arborization was calculated by the number of dendrites crossing each circle of 10μm radius around the soma (Sholl’s rings). Scale bar = 50 μm. Significant differences compared with P60a, P90b, P120c, or CTL group* (p < 0.05 by two-way ANOVA and Tukey post-test).
