人们普遍认为,与其他哺乳动物物种相比,人类的嗅觉较差。然而,这一观点并非来自人类嗅觉的实证研究,而是来自世纪一位著名的解剖学家的假设,即人类自由意志的进化需要大脑嗅球的比例大小减小。人类的嗅球实际上在绝对意义上是相当大的,并且包含与其他哺乳动物相似数量的神经元。此外,人类具有出色的嗅觉能力。我们可以检测和区分一系列特殊的气味,我们对某些气味比啮齿动物和狗更敏感,我们能够跟踪气味踪迹,我们的行为和情感状态受到我们嗅觉的影响。
It is commonly believed that humans have a poor sense of smell compared to other mammalian species. However, this idea derives not from empirical studies of human olfaction but from a famous nineteenth century anatomist’s hypothesis that the evolution of human free will required a reduction in the proportional size of the brain’s olfactory bulb. The human olfactory bulb is actually quite large in absolute terms and contains a similar number of neurons to other mammals. Moreover, humans have excellent olfactory abilities. We can detect and discriminate an extraordinary range of odors, we are more sensitive than rodents and dogs for some odors, we are capable of tracking odor trails, and our behavioral and affective states are influenced by our sense of smell.
