Tongue map

[3] Boring replotted and normalized the graphs from the original paper, which were meant to show the taste thresholds of different parts of the tongue.

[8] Into the late 1990s, tongue map experiments were a teaching tool in high school biology classes.

They then were instructed to touch those taste strips on different areas of their lab partner's tongue and record the (proper) sensation result.

[10] In 1974, Virginia Collings investigated the topic again, and confirmed that all the tastes exist on all parts of the tongue.

Prior to this, A. Hoffmann had concluded in 1875 that the dorsal center of the human tongue has practically no fungiform papillae and taste buds,[12] and it was this finding that the diagram describes.
