你的舌头能像鼻子一样闻气味
No, this doesn't mean you should stop and lick the flowers — but our senses of taste and smell may be even more entangled than we once thought. In a study published in April, scientists exposed lab-grown human taste cells to odor molecules and found that the cells reacted to scents in the same way that the smell-sensing cells in our nasal passages do. When an odor molecule touched down on one of the taste cells, the chemical plugged into a receptor on the cell's surface. In the body, the interaction between the odor and receptor would normally trigger a chain reaction inside the cell, causing it to shoot off a message to the brain.
不，这并不意味着你应该停下来舔一舔花朵来闻香味——不过，我们的味觉与嗅觉之间的关联可能比我们以前想象的更加复杂。在今年4月发表的一项研究中，科学家把实验室培育的人类味觉细胞暴露在气味分子中，结果发现这些细胞对气味的反应与我们鼻腔中嗅觉细胞的反应一样。当一个气味分子接触到一个味觉细胞时，这种化学物质会进入到细胞表面的受体中。在人体内，气味与受体之间的相互作用通常会触发细胞内的连锁反应，导致细胞向大脑发出信号。
