Rats pretrained for preference testing and injected with LiCl showed a reduction of saccharin preference in a test with a novel saccharin solution paired with water given 15 min following the injection. Previous exposure to the saccharin solution precluded this selective depression of drinking. In a second experiment, using rats naive to saccharin, insulin injection produced an increase, 2-DG and hypertonic NaCl produced a decrease, and saccharin injection produced no change in saccharin preference.
