In particular, there are two main model of peripheral taste coding: a labelled-line model, which posits that each taste receptor codes for a specific taste quality (sweet, sour, salty, bitter, umami); and an across-fiber model, which proposes that taste perception arises from the combined activity of multiple unspecific taste receptors.

The taste is commonly related to other, more negative, tastes such as bitter and sour due to how unpleasant the taste is for humans. Richard Mattes, a co-author of the study, explained that low concentrations of these fatty acids can create an overall better flavor in a food, much like how small uses of bitterness can make certain foods more ...
The myth of the tongue map: that 1 tastes bitter, 2 tastes sour, 3 tastes salty, and 4 tastes sweet. The tongue map or taste map is a common misconception that different sections of the tongue are exclusively responsible for different basic tastes.
A taste receptor or tastant is a type of cellular receptor that ... lacks introns and codes for a GPCR protein. [10 ... with many gaps due to non-existent genes ...
In both humans and rats, taste sensitivity changes with body weight, especially sweet and fat taste qualities that signal high energy availability. The nucleus tractus solitarii (NTS), which includes the gustatory nucleus, has neurons that express many different receptors that inform organisms of their internal state and are involved in the ...
Taste buds are clusters of taste receptor cells, which are also known as gustatory cells. [1] The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue , soft palate , upper esophagus , the cheek , and epiglottis .
The electronic tongue uses taste sensors to receive information from chemicals on the tongue and send it to a pattern recognition system. The result is the detection of the tastes that compose the human palate. The types of taste that are generated are divided into five categories sourness, saltiness, bitterness, sweetness, and umami (savoriness).
TAS2R38 is a bitter taste receptor; varying genotypes of TAS2R38 influence the ability to taste both 6-n-propylthiouracil (PROP) [5] and phenylthiocarbamide (PTC). [6] [7] Though it has often been proposed that varying taste receptor genotypes could influence tasting ability, TAS2R38 is one of the few taste receptors shown to have this function ...
