In another experiment the researchers find that mice  bitter   in their tongues  but then  make it more     by switching on the sweet    in the brain as were there nothing better.

The results appeared in the journal Nature. R. suggest that a lot of basic judges about our taste, sweet means good, bitter means bad, are actually   that air of the brain.
