<P> The tongue map or taste map or tongue taste or map map is a common misconception that different sections of the tongue are exclusively responsible for different basic tastes . It is 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 different parts are more sensitive to certain tastes . </P> <P> The theory behind this map originated from a paper written by Harvard psychologist D.P Hanig, which was a translation of a German paper, Zur Psychophysik des Geschmackssinnes, which was written in 1901 . The unclear representation of data in the former paper suggested that each part of the tongue tastes exactly one basic taste . </P>
