Taste
Captions available
The idea
Taste is the transduction of dissolved chemicals by receptors detecting sweet, sour, salty, bitter, and umami.
In practice
A bitter compound triggers receptors that produce rejection before any learning has occurred.
Where people slip
Taste receptors are not arranged in a tongue map by region. That diagram is a long-corrected error.
