After leading to a glomerulus, these neurons synapse with mitral cells, which go on to send signals to the brain.

在通过肾小球后，这些神经元与二尖瓣细胞突触，二尖瓣细胞继续向大脑发送信号。

So for each mitral cell, there are any number of olfactory axons synapsing with it, each representing and identifying a single volatile chemical.

所以对于每个二尖瓣细胞，有任意数量的嗅觉轴突与其突触，每个代表并识别一种挥发性化学物质。

So, once a mitral cell picks up its signal from an olfactory neuron, it sends it along the olfactory tract to the olfactory cortex of the brain.

因此，一旦二尖瓣细胞接收到来自嗅觉神经元的信号，它就会沿着嗅道将其发送到大脑的嗅觉皮层。

Inside the glomerulus, the olfactory axons meet up with the dendrites of another kind of nerve cell, called a mitral cell, which relays the signal to the brain.

在肾小球内，嗅觉轴突与另一种神经细胞的树突相遇，称为二尖瓣细胞，将信号传递到大脑。

As a result, every combination of an olfactory neuron and a mitral cell is like a single note, and the smell coming off of this pizza triggers countless of those combinations, forming a delicious musical chord of smells.

因此，嗅觉神经元和二尖瓣细胞的每一个组合都像一个音符，披萨散发出的气味会触发无数这样的组合，形成美味的气味音乐和弦。
