The preference of sucrose, saccharin and salt solutions to water was analyzed during 5 days in rats with bilateral section of the lingual nerve comprising the taste nerve--chorda tympani. In the process of the analysis of daily consumption and choice of solutions, different types of behavioural reactions were found: stable preference and change of preference. The number of rats preferring NaCl was greater among the animals with sectioned lingual nerve than among sham-operated control rats and rats with ligated ducts of submaxillary and sublingual salivary glands. The number of rats with the lingual nerve section preferring sucrose or saccharin solutions to water was equal to that among the sham-operated rats. At the same time the mean volume of sucrose solution taken in daily by rats with sectioned lingual nerve was twice as great as the volume of saccharin, drunk by the same animals. The role of taste in the process of choice and preference of NaCl to sweet solutions is discussed.
在舌神经（包含味觉神经——鼓索神经）双侧切断的大鼠中，分析了蔗糖、糖精和盐溶液相对于水的偏好情况，为期5天。在分析每日溶液消耗量和选择情况的过程中，发现了不同类型的行为反应：稳定偏好和偏好改变。舌神经切断的动物中，偏好氯化钠的大鼠数量多于假手术对照大鼠以及颌下腺和舌下腺导管结扎的大鼠。舌神经切断的大鼠中，相对于水更偏好蔗糖或糖精溶液的大鼠数量与假手术大鼠中的数量相当。同时，舌神经切断的大鼠每日摄入的蔗糖溶液平均量是同组动物摄入糖精溶液量的两倍。文中讨论了味觉在选择过程以及氯化钠相对于甜味溶液的偏好过程中的作用。
