Figure 2.
Duration and frequency of bouts of behavior during the first 40 min after ethanol consumption. (A) The mean duration of a bout of behavior during each 5 min interval ± SEM is shown for walking, upside down, stopped and grooming behavior. (B) Mean frequency (number of times a bout of the behavior was observed) of bouts of walking, upside down, stopped and grooming for each 5 min interval. Mean bout duration and frequency for the entire 40 min observation were compared to the control (0%) for subjects given each ethanol treatment for each behavior. Bout durations were compared with a Dunnett’s test and frequencies were compared with a least-squares contrast. Asterisks (*) indicate significant P-values (* p < 0.05, ** p < 0.01 *** p < 0.005).
