Development of locomotor sensitization following repeated administration of ethanol (2.5, 3.0 or 3.5 g/kg; n’s=10–15) or saline (n’s=18–22) ± SEM in D2 and B6 mice. a-b) B6 adults showed an effect of day only following repeated administration of 2.5g/kg (*, p<0.05), whereas B6 adolescents showed this within-subjects sensitization effect following all doses (*, p’s<0.05). c-d) D2 adults showed within-subjects (*) and between-group (†) sensitization following all doses (p’s<0.001), whereas D2 adolescents exhibited an effect of day following 2.5g/kg and 3.0g/kg (p’s<0.001) and between group sensitization following 2.5g/kg only (p<0.01).
