The smell-threshold reduction was “preclinical,” he explains, meaning the children wouldn’t notice the change but it could be picked up with testing.

If there are smells that have an aura of particular time and place indelibly ingrained in their olfactory image, patchouli is certainly one of them.
味道大多是觉察到气味的结果，因此菜谱强调当有嗅觉障碍时的正常感官——香味、质感和温度感。
Taste is mostly a result of odor detection, so the recipes emphasize spice, texture and temperature, sensations that remain unimpaired even when smell malfunctions.

多尔曼指出，例如大鼠鼻腔有一半的面积附有嗅细胞，而对于人类来说，这种嗅觉接收区就小得多，他说——“也就鼻腔的3% - 5%吧。”
For instance, Dorman notes that half of the nasal cavity of a rat is lined with olfactory-system cells. In humans, this receptive area is much smaller, he says - "only about 3 to 5 percent."
动物拥有更敏锐的感官被详尽的记录着，狗有非同寻常的嗅觉，鸟可以依据天空的情况进行迁徙，蝙蝠利用声波定位食物。
The fact that animals have keener senses than humans is well-documented. Dogs have a remarkable sense of smell, birds can migrate using celestial cues, and bats can locate food with echoes.
