空气流入一个鼻孔比流入另一个鼻孔更大，因为一个鼻孔有轻微的鼻甲骨肿胀。吸入更多空气的鼻孔每隔几个小时就会从左边切换到右边，然后再切换回来，但是这种切换对嗅觉的影响还不清楚。在这里，我们表明，鼻孔之间的气流差异导致每个鼻孔对不同的气味最佳敏感，因此每个鼻孔向大脑传达略有不同的嗅觉图像。
The flow of air is greater into one nostril than into the other because there is a slight turbinate swelling in one,,. The nostril that takes in more air switches from the left to the right one and back again every few hours,,, but the effect of this switching on the sense of smell has been unclear,. Here we show that this difference in airflow between the nostrils causes each nostril to be optimally sensitized to different odorants, so that each nostril conveys a slightly different olfactory image to the brain.
