Effect of thyroxine on taste hedonics in rat.

ABSTRACT

1. The hedonic response to sweetness was tested in 12 thyroxine treated rats using the method of single-bottle brief-exposure to sweet (saccharin) solution. 2. Consumption of the sweet solution was significantly more following administration of thyroxine than during the control period. 3. The 1-hr consumption of saccharin solution appeared to be more sensitive to thyroxine than the 5-minute consumption.
