Alcohol intake levels in FSL and FRL animals. Animals had voluntary access to alcohol for a total of n = 33 IA20E alcohol sessions prior to the OSU experiment. Both FSL and control-FRL animals escalated significantly their alcohol intake as the result of time/drinking session. However, there was no significant difference in alcohol intake between FSL and controls at any given session (n = 10 animals per group; n = 1 outlier alcohol session). Graph data are presented as mean ± SEM and were analyzed by a mixed-effects model.
