Visualization analysis of differentially expressed genes in hippocampus and hypothalamus. a, b Heatmap based on RNA-sequencing data of the exercise group compared to the sedentary group in hippocampus and hypothalamus, respectively. c, d Volcano map based on RNA-sequencing data of the exercise group compared to the sedentary group in hippocampus (up-regulated: 53, down-regulated: 49) and hypothalamus (up-regulated: 24, down-regulated: 40), respectively. Red, blue, and white colors respectively represent the relatively high, low, and equal expression in heatmaps and volcano maps. n = 5 per group, p < 0.05
