    Notes: Abstract Gamma-butyrolactone (GBL) induced longer loss of righting reflex in mice (LS-line) selectively bred for greater sensitivity to ethanol than in less sensitive SS-line mice. GBL also induced a three-fold greater increase of brain dopamine levels in LS than in SS mice. Among three inbred strains, GBL-induced loss of righting reflex was greater in BALB/c, and greater in DBA/2 than in C57BL/6 mice. A low dose of GBL produced biphasic effects on locomotor activity. Both an initial depressant action and a later increase in activity were greater in LS than in SS mice. These GBL effects on activity were modified in a genotypedependent fashion by amphetamine. Results of these experiments as well as greater catalepsy-inducing properties of haloperidol in SS mice suggest that genotypic influences on motor reactivity to ethanol may be modeled by GBL effects on brain dopamine systems.

    A biometrical genetic analysis of ethanol response in selectively bred Long-Sleep and Short-Sleep mice (1984)

    Notes: Abstract A classical Mendelian cross was derived from Long-Sleep (LS) and Short-Sleep (SS) mice, lines selectively bred for differences in response to hypnotic doses of ethanol (ETOH). Biometrical genetic procedures applied to the selection phenotype, namely, duration of the ETOH-induced loss of the righting reflex, suggest that a simple additive genetic system controls this depressant response. Sex differences were present in the Mendelian cross generations that had the longest duration responses. An estimate of the number of loci differentiated by the selection was nine. Blood ethanol levels at the time of regaining the righting reflex in the seven genotypes of the Mendelian cross showed that the selection operated solely by changing tissue sensitivity to ethanol.
