The olfactory bulbs transmit that information back to the brain.

大脑嗅球将嗅觉信息传输回大脑。

The vapours pass through your mouth, around the soft palate, into the nasal cavity and to the olfactory bulb.

蒸汽通过口腔，绕过软腭，进入鼻腔和嗅球。

Once they're detected by receptors in your nose, the signal heads straight to your olfactory bulb, the smell-analyzing region in your brain.

一旦气味被鼻子里的接收神经察觉，讯号将会直达嗅球，也就是你脑中分析味道的区域。

One of the big surprises was the size of the olfactory bulbs, part of the brain associated with processing information about smells in the environment.

让我们吃惊的是，霸王龙大脑嗅球的大小，大脑的一部分与处理环境中的气味信息密不可分。

In fact, various studies have found the olfactory bulb sends more neurons to more areas of our brain than our hearing or vision.

事实上，各种研究发现， 嗅球将更多的神经元发送到我们大脑的更多区域， 而不是我们的听觉或视觉。

When an odor molecule binds to a scent receptor, it sends an electrical signal from the sensory neurons to our brain's olfactory bulbs.

当气味分子与气味受体结合时，它会从感觉神经元向我们大脑的嗅球发送电信号。

Then evidence began to emerge of young neurons in the brains of adult rats and mice, -specifically in the olfactory bulb, which processes smell, and the dentate gyrus.

随后，成年大鼠和小鼠的大脑中出现了年轻神经元的证据，特别是在处理气味的嗅球和齿状回中。

See, the olfactory bulb, which processes odors, is connected to two important structures involved in memory and emotion: the hippocampus and the amygdala.

你看，处理气味的嗅球与记忆和情感中涉及的两个重要结构相连：海马体和杏仁核。

Roja Dove, a perfumer, told the BBC that when we are born, the olfactory bulb, which is the area in our brain that processes smell, is empty.

调香师罗哈·多夫（Roja Dove）告诉BBC， 当我们出生时， 嗅球，也就是我们大脑中处理气味的区域， 是空的。

These neurons migrate down from the olfactory placode and get embedded in the cribriform plate, which is a bone plate that separates the nasal cavity from the brain, forming the olfactory bulb.

这些神经元从嗅觉基板迁移下来，并嵌入筛板中，即将鼻腔与大脑隔开的骨板，从而形成嗅球。
