Scientists discover how animals taste, and avoid, high salt concentrations
Date:2/13/2013

kin pie? How do our taste sensations change over time? The answers are in the firing of neurons in the brain.

With the taste receptor cells in hand, the researchers have recently turned to brain imaging, mapping the neurons that receive information from the tongue's taste buds. The map was a surprise. Instead of finding the neurons scattered, as the taste receptor cells on the tongue are, they found discrete hotspots of the brain for each of four tastes: sweet, bitter, umami, and salty (sour has not yet been located).

Ultimately, they hope to understand how the firing of these neurons produces the sensations we call tastes.
