Mapping the Locations of Taste Receptors
30:30 - 40:25 (09:55)
Researchers have identified receptors for all five basic taste classes, including sweet, bitter, salt, umami, and sour, which can now be rigorously mapped to understand where they are found in the tongue. Additionally, there may be somatosensory cells that respond to the mechanical stimulation of fat molecules rolling on the tongue to create the perception of fat.

The perception of "fat taste" may not necessarily stem from a dedicated receptor for fat, but rather from mechanical stimulation of fat molecules on the tongue, according to researchers.

Summary
The perception of "fat taste" may not necessarily stem from a dedicated receptor for fat, but rather from mechanical stimulation of fat molecules on the tongue, according to researchers. This suggests that "fat taste" may actually be a form of mechanosensory perception.
