R. and his colleagues found that  taste without a tongue at all. Simply by stimulating the taste part of the brain, the  cortex. They  experiment in mind with a special sort of  plan, a   table that turn the neurons on with a pose of lazar light.

And by switching the bitter sensing part of the brain, they were able to  as if they were tasting something better, even though absolutely nothing better was touching the tongue of the mice.

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.

What we are doing here is adding the sweetness but only adding it in the brain  not in what we were giving to the mouth.      Think adding sugar in your coffee but doing it only in you mind. 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. And as for that virtual sugar for your coffee idea.

      This would be something would be applied to human. But today’s science fiction may be tomorrow’s artificial
