Changes in c-Fos expression in each brain region before and after training. Representative image of c-Fos expression in the a septum, c striatum, and e motor cortex of mice before and after training. Scale bars (black) = 50 μm. The c-Fos expression values in the b septum, d striatum, and f motor cortex. Data are presented as mean ± standard error (n = 5). Unpaired t test was used
