Rat lines selectively bred for high ethanol consumption consume more saccharin solution than do their low-ethanol-consuming counterparts. The present study utilized the technique of reciprocal selection to examine the reliability of the saccharin/ethanol relationship; specifically, consumption of 1-10% ethanol solution was measured in rats selectively bred for high vs. low saccharin consumption (Occidental HiS and LoS lines). HiS rats consumed more ethanol than did LoS rats. These results support the idea that individual differences in ethanol and saccharin consumption share some common mechanism(s).
