Differences in rat's licking rate for saccharin solution and water

1998 Japanese Journal of Animal Psychology  
Long-Evans rats were trained to lick saccharin solution or tap water through a drinking tube. Two experiments examined whether the burst licking rate is faster for saccharin than for water under a condition of water deprivation. In. Experiment 1 the burst rates of two of the three subjects were faster for saccharin than water. Volume per lick was smaller for saccharin. And the decreasing period of the burst rate was confirmed during the initial period of drinking. Experiment 2 investigated the

The difference of the burst rates for saccharin and water was not related to the distance between the opening and the spout.
