[Effect of taste deafferentation on the preference for solutions of saccharose, saccharin and salt in rats].
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.
