Physiological correlates of ethanol self-selection by rats

Abstract

High-drinker and low-drinker rats were given 1.2g/kg of ethanol intraperitoneally. Subsequent blood-alcohol measurement showed that low-drinker rats had a significantly higher level than high-drinker rats at 15 min postinjection. Previous studies measured ethanol levels starting at 60 min postinjection and reported no differences for high drinkers and low drinkers. The present results are interpreted to account for the observed behavioral differences between high-drinker and low-drinker rats. © 1974, Psychonomic Society, Inc.. All rights reserved.
