This olfactory sense develops in the womb.(這一嗅覺在子宮內形成。)

Few tests of olfactory senses are as intense as those in the beauty and fragrance departments of large stores.(嗅覺感官的體驗也像大型賣場中美容和香水專柜一樣的強烈。)

Neurogenesis also takes place in the olfactory bulb, which is involved in processing smells.(神經發生也發生在負責處理氣味的嗅球。)

While it is true that the olfactory powers of humans are nothing like as fine as those possessed by certain animals, they are still remarkably acute.(雖然人類的嗅覺能力確實不如某些動物靈敏，但也是非常敏銳的。)

The information conveyed by the olfactory signals on a buck rub make it the social equivalent of some auditory signals in other deer species, such as trumpeting by bull elk.(雄鹿的摩擦印記發出的嗅覺信號所傳遞的信息，使其與某些其他鹿類的聽覺信號，比如公麋鹿的號角聲，產生了相同的社會效果。)

Based on these findings, Keller suspects that each person has an olfactory blind spot.(根據這些發現，凱勒推斷，每個人都有一個嗅覺盲區。)

For example, studies show that even brief periods of odorant stimulation produce transient reductions in receptors in the olfactory epithelium, a process termed "receptor fatigue".(例如，研究表明，即使是短暫的氣味刺激也會導致嗅覺上皮細胞中受體短暫的減少，這個過程被稱為“受體疲勞”。)

This has implications for olfactory research.(這對嗅覺研究有一定的啟示。)

Whether an olfactory component such as an individual fragrance could be added to the haptic elements is debatable.(能否把個性化的香味等嗅覺成分加進觸覺元素里還很成問題。)
