Or maybe the bait traps triggered the spread of rare genetic variations in roach taste cells
left over from before the species moved in with people.
are located in clusters called taste buds, which in turn are found in papillae, the raised bumps visible on the tongue's surface.
But finding taste cells
on land animals wasn't easy.
The presence of the KATP channel suggests that taste cells
may play a role in regulating our sensitivity to sweet taste under different nutritional conditions.
Non-tasters are simply those people with a very low number of taste cells
and who essentially perceive the world, at least from a taste perspective, as dulled.
An American biotechnology company has discovered ``bitter blockers'' which stop production of a protein released by taste cells
Each taste bud is an onion-shaped cluster of 50 to 100 taste cells
," says scientist Julie Mennella at Philadelphia's Monell Taste Laboratory.
Recent studies with rats have shown that fats were capable of causing electrical changes in taste cells
of rats, indicating there was a chemical detection system there.
The taste cells
then send information about the chemicals along the nerves to your brain, and your brain tells you what you are tasting.
He found that fatty acids -- an important component of fats -- produce a noticeable response in the taste cells
of laboratory rats.
Taste receptors, which are proteins found on the surface of taste cells
, interact with food ingredients and allow us to experience different taste sensations," Karanewsky explained.
Looking further into the action of the protein produced by Ir76b, the team found that it is a channel with a pore that lets sodium pass into the taste cells
of the sensilla.
