In the present series of studies, the running speed of rats in a runway was used to measure appetitive motivation for different concentrations of salt solutions. We found that when rats were thirsty, they were not interested in running for concentrated salt solutions; when they were rendered salt hungry by mineralocorticoid treatment in addition to the thirst, or even without thirst, they ran vigorously for salty tasting solutions, as high as 24% NaCl. The running speed is correlated with the degree of the mineralocorticoid treatment and the salt concentration. Moreover, drinking 5 cc of a 3% NaCl solution before the runway test decreases the running speed of the mineralocorticoid-treated rat. The experiments are discussed in the context of the effects of hormonal events on the movitation to ingest salt solutions.
在本系列研究中，利用大鼠在跑道上的奔跑速度来测量其对不同浓度盐溶液的食欲动机。我们发现，当大鼠口渴时，它们对为获取浓缩盐溶液而奔跑并不感兴趣；当通过盐皮质激素处理使它们除口渴外还产生缺盐感时，或者甚至在不口渴时，它们会积极地为有咸味的溶液奔跑，溶液的氯化钠浓度高达24%。奔跑速度与盐皮质激素处理的程度和盐浓度相关。此外，在跑道测试前饮用5毫升3%的氯化钠溶液会降低经盐皮质激素处理的大鼠的奔跑速度。本文在激素事件对摄取盐溶液动机的影响这一背景下对这些实验进行了讨论。
