摘要：

Taste sensitivity and responsivity, two-tastant and taste-mixture discrimination performance, and taste preferences were examined prior to and after the selective desalivation of 48 male Long-Evans rats. Altered preference behavior was observed in rats after removal of the major salivary glands, as well as after removal of only the submandibular-sublingual complexes. In 9 of 12 desalivated rats, decreased sensitivity and increased responsivity to near-threshold sodium chloride solutions were observed, although these changes were less than one-half an order of magnitude. No between-group differences in performance on two-tastant and taste-mixuture discrimination tasks were observed. These results suggest that decrements in absolute sensitivity do not result in concomitant deficits in the discrimination of taste qualities. © 1990.
