Psychological stress exposure to aged mice causes abnormal feeding patterns with changes in the bout number

Figure 1. Changes in locomotor activity in young and aged mice after fasting or exposure to novelty stress/water avoidance stress. (A) left: average voluntary movements after 24-h fasting in the dark/light phase, right: the 24-h changes after 24-h fasting in young mice, (B) left: average voluntary movements after novelty stress in the dark phase, right: the 24-h changes after novelty stress in young and aged mice, (C) left: average voluntary movements after water avoidance stress (WAS) in the dark phase, right: the 24-h changes after WAS in young and aged mice. *, ***; P < 0.05, 0.001 vs. fed or age-matched basal/control mice, ##, ###; P < 0.01, 0.001 between young and aged mice, n = 8, 14–16, or 7–8.
