Have you ever had that gut reaction to your surroundings, some physical sensation that something isn’t quite right? Maybe a squirmy, uneasy feeling in your stomach or an acrid taste on your tongue that makes you want to leave the scene? When the nematode C. elegans encounters an offensive sensation—whether a pungent, potentially dangerous odor (such as those associated with fungal parasites), e...

Response of pigs to bitter-tasting compounds.

Pigs detect and avoid taste compounds that humans perceive as bitter-tasting. A dose-response to varying concentrations of bitter tastants can be measured.

Rats fail to discriminate quinine from denatonium: implications for the neural coding of bitter-tasting compounds.

Recent molecular findings indicate that many different G-protein-coupled taste receptors that bind with "bitter-tasting" ligands are coexpressed in single taste receptor cells in taste buds, leading to the prediction that mammals can respond behaviorally to structurally diverse "bitter" tastants but cannot discriminate among them. However, recent in situ calcium-imaging findings imply that rat ...
