Schedule-induced polydipsia in desalivate rats as a function of percent free-feeding weight☆

摘要: Abstract Desalivate and control rats maintained at 80% of free-feeding weight were delivered 45 mg pellets on a fixed-time 1-min schedule for 14 sessions polydipsia testing. showed immediately, but had lower asymptotic intakes than controls. Over the postpellet bout size frequency increased gradually in controls remained stable desalivates. Body increases to 105% over 21 additional resulted decreased which similar desalivates In both as function body increases, while only decreased. The immediate acquisition was attributed prandial drinking pattern learned during postoperative recovery, whereas attenuated levels overhydration consequent precise size.
