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.

Taste is the perception stimulated when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with the sense of smell and trigeminal nerve stimulation (registering texture, pain, and temperature), determines flavors of food and other substances.
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.
The gustatory cortex is the primary receptive area for taste. The word taste is used in a technical sense to refer specifically to sensations coming from taste buds on the tongue. The five qualities of taste detected by the tongue include sourness, bitterness, sweetness, saltiness, and the protein taste quality, called umami.
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 .
Phase-of-firing code is a neural coding scheme that combines the spike count code with a time reference based on oscillations. This type of code takes into account a time label for each spike according to a time reference based on phase of local ongoing oscillations at low [ 39 ] or high frequencies.
“The research revealed that ‘cheese’ had become a ‘taste code’ among consumers in their teens and twenties,” wrote a marketing representative for the company in an email. “Inspired ...
T1R2 - Taste receptor type 1 member 2 is a protein that in humans is encoded by the TAS1R2 gene. [ 5 ] The sweet taste receptor is predominantly formed as a dimer of T1R2 and T1R3 by which different organisms sense this taste.
