Fasting increases time in food zone and consumption of peanut butter chip reward. Comparison of ad libitum fed and 18 h fasted mice in the reward-baited light/dark box (A–D), n = 18; reward-baited open field test (E–H), n = 12; and reward-baited elevated plus maze, (I–K), n = 20–25. FZ, food zone; ^*p < 0.05, ^**p < 0.01, independent measures t-test.
