Correlation between hippocampal nNOS protein expression levels and body weight (a, b, c, and d), and relative visceral fat mass (e, f, g, h) at 2 weeks (a, e), 6 weeks (b, f), 7 weeks (c, g), and 12 weeks (d, h). Open circles, SD group; light gray circles, HFD group; dark gray circles, HFD + Ex group. Lines in the scatter plots show significant correlations (by Pearson’s product–moment correlations test)
