Soda contains a feeling of pain

Scientists have found that carbonated beverages activates pain receptors in the nose. Because of this, drinking soda, and there is also a burning sensation as when using some hot spices, such as mustard or horseradish.

Experts from the University of Southern California, decided to "decipher" the most complex taste sensation soda . They found that these drinks are activated in a human nose are the same sensors that mustard and horseradish. Nasal nerves are utilized as a reaction to the sensation of pain, pressure and temperature changes of the skin in the nose and the mouth, as reported by researchers.

This discovery demonstrated that   aeration   also causes a burning sensation. "These drinks give rise to a person two distinct sensations, - says senior study author Professor Emily Liman. - It's about a characteristic sour taste and burning sensation. We all experience these unpleasant tingling when aeration   falls across his throat too fast. But until recently we did not know which cells and which molecules in these cells cause pain that we experience when we drink soda ".

These studies are published in the journal Journal of Neuroscience for September 29. Authors in vitro passed saliva containing   soda Through nerve cells that have been extracted from the nose and mouth. It was found that one type of cell activates the same nociceptors and soda , And mustard.

Contained in this cell type TRPA1 gene was the "switch" which is activated by the carbon dioxide contained in soda.
