taste map

Many of you may have learned in school that the tongue has different tastes depending on where it is located.

In 1901, German scientist D.P. Hoenick proposed that different parts of the tongue produce different taste sensations. Based on this research, a "taste map" was later created.
We now know that all tastes are sensed across the tongue, with negligible regional differences.
With one exception, the middle line of the tongue is taste blind.
