Amount of ethanol consumed by rats trained in a voluntary intake protocol. The ethanol containing solution was made accessible to the animals between 11:00 and 13:00, every day for 3 weeks. The first 10 days represent a training phase with constant concentration of ethanol and decreasing concentration of sucrose. The amount of ethanol consumed was calculated every day as difference between the weight of the bottles before and after consumption session and is expressed as Mean ± SEM of 20 rats per group. ap < 0.05, a’p < 0.01 vs. GH.
