When sugar touches the tongue, it sends a message to the ‘taste center’ of the brain that you had something which is sweet. This in turn sends a message to other part of the brain that says having sweet is good for health. This phenomenon is problematic for any person who is trying to shed out the extra pounds, but now, the scientists have discovered a way to disrupt this by conducting a study on mouse brains.

Chances are that if you give a mouse a sweet item such as cookie, it may not ask for another one. Well, this is only possible if you first rewire its brain properly. In the study, published in the Nature journal on Wednesday, the researchers of Columbia University disrupted the amygdale, the brain region which is responsible to produce pleasant as well as unpleasant experience associated to taste, and discovered that the mice was still able to detect sweet and bitter flavours but was not able to express for one taste or could develop a preference for the other taste. This shows that their taste is not related to pleasurable experience of taste inherently. Instead, it looks like the two experiences were processed in different regions of the brain.

Moreover, the team were also discovered that they could manipulate the way the mice could process tastes, making even plain water appealing to the mice and altering the way they experienced bitter as well as sweet tastes.

The study shows that tasting and enjoying are ruled by two different brain regions in the mice at least. It shows that pleasure and flavour do not hold a link entirely although most of us take this phenomenon for granted many times. By getting more information on such a demonstration, which the researchers say is the same for the humans; they hope to gain further insight on the eating disorders that most people face.
