Comparison of levels of alcohol consumption and of alcohol preference in transgenic mice used
| Mouse lines | Alcohol intake (g/kg/24 h) | Alcohol preference (%) | |
|---|---|---|---|
| D1-eGFP | 4.90 ± 0.50 | 27.88 ± 3.49 | n = 11 |
| D1-Cre/DsRed | 16.08 ± 1.23 *** | 53.69 ± 3.48 ### | n = 17 |
| D2-Cre/DsRed | 15.88 ± 0.75 a | 57.52 ± 1.97 b | n = 19 |

All mice were exposed to alcohol using the intermittent access to 20% alcohol two-bottle choice drinking procedure.
