The olfactory bulbs transmit that information back to the brain.

大脑将觉信息传输回大脑。

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。

A glomerulus is a clump of nerve tissue.

一个是一团神经组织。

You know, they access the olfactory bulb.

你知道，它们会接触到。

For example, here are the paths extending from human olfactory peduncle to other regions.

例如，以下展示的是从人类延伸至其他区域的路径。

Different odor receptors transmit signals to different glomeruli.

不同的觉受体将信号传递给不同的。

The glomeruli then send that information to your brain's cortex.

然后将这些信息传递给大脑皮层。

And we also have a part of the brain called the olfactory cortex, which is responsible for analyzing what we smell.

我们大脑中也有一部分叫，负责分析我们闻到的气味。

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，霸王龙大脑的大小，大脑的一部分与处理环境中的气味信息密不可分。

So this is just an image of the olfactory peduncle in the human on the left and the dog on the right.

因此，这是一幅左侧显示人类，右侧展示狗的图像。

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

，各种研究发现， 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.

当气味分子与香味受体结合时，它会从感觉神经元向我们大脑的发送一个电信号。

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，处理气味的与记忆情感中涉及的两个重要结构相连：海马体杏仁核。

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齿状回中。

During the 1870s, Italian biologist and pioneering neuroanatomist Camillo Golgi produced detailed descriptions of the spinal cord and the brain's olfactory lobe, cerebellum and hippocampus.

19世纪70年代，意大利生物学家、神经解剖学先驱卡米洛·高尔基对脊髓及大脑的、小脑海马体进行了详细描述。

You can imagine it's like these glomeruli light up when they get a signal, and the pattern of this lighting depends on the chemical makeup

你可以想象这就像这些在接收到信号时会亮起来，而这种亮起的模式取决于化学成分。

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， ，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。

There are a few places you produce new neurons, like the olfactory bulb, the dentate gyrus, or the hippocampus, a few places, but these are far and few between.

有一些地方会产生新的神经元，比如、齿状回或海马体，但这些情况非常罕见。

Scientists do have a theory of how the virus could travel to the brain: from the nose, and then upward through the olfactory bulb, which connects to the brain.

科学家确有一个理论解释病毒是如何到达大脑的：从鼻子出发，然后通过与大脑相连的向移动。
