影响反应强度的一个简单因素，就是产生神经冲动的神经元数量，神经元越多，反应强度越大。

So, one simple way to code intensity is the number of neurons firing; the more neurons the more intense.

气味物质作用于嗅细胞，产生神经冲动经嗅神经传导，最后到达大脑皮层的嗅中枢，形成嗅觉。

Odour material action at smell cell, generation nerve impulse is conducted via olfactory nerve, reach the smell center of pallium finally, form smell.

如果达到了一定的数量，比如超过60之类的，神经元便会产生神经冲动，神经冲动沿轴突传递，右边的是轴突。

And then if you get a certain number, plus 60 or something, the neuron will fire and it fires along the axon, the thing to the right.

These--Again, the chemicals could excite the other neuron bring up the chances it will fire, or inhibit the other neuron .

再强调一遍,这些化学物质可使另一个神经元变得兴奋,提高该神经元产生神经冲动的可能性,也可抑制另一个神经的兴奋性

This infinitesimal gap-- and this gap is known as a synapse-- and what happens is when a neuron fires, an axon sends chemicals shooting through the gap.

这个极小的缝隙,这个缝隙就叫做突触,当神经元产生神经冲动后,轴突会释放出能够穿透缝隙的化学物质
