嗅觉感知远比我们想象的更重要。一项在小鼠身上开展的研究表明,嗅觉的好坏与免疫系统是否正常运行有关。近几年,科学家陆续找到了免疫系统与嗅觉系统之间存在关联的证据。比如,女性似乎更喜欢那些携带着和自身免疫系统基因不同的男性所散发出的气味;免疫系统的健康与否可能会影响人的性格。 Smell perception is more important than we think. A study in mice showed that the quality of the olfactory is related to the normal functioning of the immune system. In recent years, scientists have found evidence of an association between the immune system and the olfactory system. For example, women seem to prefer the smell of men who carry genes different from their own immune system; the health of the immune system can affect one’s personality.
