Abstract
In water-deprived rats and mice, animals trained to the test situation spent more time in drinking than naive animals (first exposure to the test situation). The time spent in drinking, either during 5 min or during 10 min was recorded. As compared to controls, benzodiazepines, phenobarbital, meprobamate, and mecloqualone increased drinking time whether the experiments were run on naive or on experienced animals [5 or 10 (in mice) and 9 (in rats) exposures in the test situation]. All drugs were injected i.p. 30 min before testing. This release of the drinking behavior was more pronounced during the last 5 min than during the first 5 min of the 10 min test session.
