ResumoA comparison was made of the licking pattern of water-deprived desalivated sham-operated and nonoperated rats on a drinkometer. During the 10-min test sessions, the animals were allowed to drink water from glass spouts and the time between licks was recorded with an interlick time distributor. The distributor was programmed to measure licks with 0.1-sec intervals and the responses were distributed in 1 of 10 bins. The results showed that rats with their salivary ducts ligated displayed a different drinking pattern than rats in the two control groups. In general, the nonoperated control rats displayed more licks with short (i.e., <0.2-sec) interlick intervals than the sham-operated and desalivated rats. The sham-operated rats, in turn, showed a faster licking pattern than the desalivated rats. These results indicate that desalivated rats have more difficulties in drinking from glass spouts than those in the other groups.
