title: Tests of adipsia and conditioned taste aversion following the intrahypothalamic injection of amylin.
abstract: Intrahypothalamic injection of amylin (AMY) was shown to reduce the intake of rat chow and water for 8 and 4 h, respectively, in schedule-fed rats. Amylin also reduced water intake to a much lesser degree in 24-h water-deprived rats. A test of the ability of AMY to form a conditioned taste aversion yielded no change in saccharin preference, as compared to controls treated with vehicle. These results suggest that although AMY has adipsic effects, the reduction in water is not of sufficient magnitude to cause the anorexia. In addition, the failure of AMY to support a conditioned taste aversion suggests that AMY does not cause anorexia by inducing malaise. Therefore, in addition to other metabolic effects, AMY may be involved in the control of food and water intake.
