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

Figure 5. Experimental schedule and schematic feeding bout. (A and B) It is shown experimental schedule. (C) Green indicates "Meal" parameters, and red indicates “Bout” parameters. It is shown a chart when meal number is 3 and bout number is 9 as an example. Each value indicates the number of times per analysis time. Feeding bout was defined as a new bout when the time without feeding was longer than 5 sec from the previous response and was equal to or greater than 0.01 g. Food consumption was considered to be a “Meal” when the feeding bouts occurred within 5 min of the previous response and the sum of the food consumed during the bout was equal to or greater than 0.02 g; when the feeding bouts were longer than 5 min apart, these were considered to be a new meal.
