Effect of instruction on image formation by olfaction and on multimodalsensory integration

这项研究表明，人类通过手部皮肤感到温暖的温度是通过同时闻到特定气味而改变的。由于气味的神经信息被传递到人类和动物共同的与情绪相关的大脑区域，我们通过观察模型动物的大脑区域的活动来研究情绪表达与嗅觉或温度感觉之间的相互关系。结果表明，感觉到某种气味或凉爽会减弱作为情绪驱动的应激反应。这表明，一些气味可能会有效地让人类的日常生活变得更加舒适。

This study suggested that the temperature at which humans feel warm through their hand skin is changed by concurrent smelling of particular odors. Since neural information on odors is conveyed to the emotion-related brain area common to humans and animals, we studied an interrelation between emotion expression and smelling or temperature sensation by observing the activity of the brain area in model animals. The results showed that perception of some odors or coolness attenuates stress response as emotion drive. These suggest that some odorants may be effective for making everyday life of humans more comfortable.
