Tongue map

Tasting-on-the-tongue

It is not true that different sections of the tongue are exclusively responsible for different basic tastes.

This is a misconception that has persisted since 1901 and has been illustrated with a schematic map of the tongue, with certain parts of the tongue labeled for each taste. Although widely taught in schools, this was scientifically disproven by later research; all taste sensations come from all regions of the tongue, although parts may be more sensitive to certain flavours.
