Mice were treated chronically with either control and ethanol injections (A, B) or liquid diet (C, D). Locomotor behavior was not altered by ethanol withdrawal (A, C) but produced a significant decrease in the center ratio (distance traveled in center zone/total distance traveled; B and D). **p<0.05 compared to control-treated mice as measured by student t-test. N’s are 13, 9 for injections and 13, 13 for liquid diet.
