[The effect of taste deafferentation on the phenomenon of pre-exposure taste solutions in rats].
After 2-day pre-exposure of rats to sucrose, saccharin or sodium chloride pairing with water (a two-bottle technique) the animals were deprived of liquid for 48 hours. After the deprivation was over, the rats were exposed to the familiar solution (a one-bottle technique) for 15 minutes. The rats which had already tried the taste solutions drank them in a greater amount in the 15-minute test as compared to those which had not been exposed to the taste solutions. In rats with bilateral deafferentation of the tongue, the preliminary testing of saccharin and sodium chloride solutions did not produce any effect on the volume intake during the 15-minute test. The increasing influence of the pre-exposure to sucrose solution could be seen both in deafferentated and in control sham-operated rats. The role played by the gustatory apparatus at the early stages of liquid intake as well as the effect of taste on short-term memory are discussed.
