phenotype observed in females
phenotype observed in males
N normal phenotype
• voluntarily consume more ethanol compared to wild-type littermates
• increase in consumption is not related to a change in taste preference as no difference in preference for saccharin or quinine is seen
• administration of an A1 receptor agonist reduces alcohol consumption and preference in mutant but not wild-type mice
• the severity of ethanol-induced motor incoordination and loss of righting reflex is reduced compared to wild-type controls
• however, blood ethanol concentrations do not differ from wild-type

nervous system
• incubation of brain slices with an A1 receptor antagonist (1,3-dipropyl-8-cyclopentylxanthine) fails to increase evoked EPSC amplitude unlike in wild-type littermate brain slices
• the frequency of spontaneous EPSCs in the striatum is increased 2.5-fold compared to wild-type littermates
• the increase in frequncy is associated with a slight but significant increase in amplitude
