The tongue map or taste map is a common misconception that different sections of the tongue are exclusively responsible for different basic tastes.

The taste buds on the tongue sit on raised protrusions of the tongue surface called papillae. There are four types of lingual papillae; all except one contain taste buds: Fungiform papillae - as the name suggests, these are slightly mushroom-shaped if looked at in longitudinal section. These are present mostly at the dorsal surface of the ...
The tongue contains taste receptors, that sends sensory information via action potential to the solitary nucleus. Then, such signal is directed towards the gustatory nucleus, which is located within the Thalamus. [12] Topography on the tongue doesn't determine the arrangement and processing of input within this nucleus.

Taste bud. The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste (flavor). [1] 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.
A taste receptor or tastant is a type of cellular receptor that facilitates the sensation of taste. When food or other substances enter the mouth, molecules interact with saliva and are bound to taste receptors in the oral cavity and other locations. Molecules which give a sensation of taste are considered "sapid". [1]
