双方躯体和自主效应可能会反射兴奋神经冲动所带来的相同的感觉年底机关。

Both somatic and autonomic effectors may be reflexly excited by nerve impulses arising from the same sensory end organs.

听觉和触觉都需要震动引起感觉神经兴奋。

Both hearing and touch, the scientists pointed out, rely on nerves set atwitter by vibration.

换句话说，当一个系统达到某个兴奋顶点，神经活动连锁地“召集”或引发下一个系统。

In other words, when one system reaches a certain peak of excitation, the nerve activity that it generates "recruits" or affects the next system along the chain.

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

Now, these signals can be either excitatory, which is that they raise the likelihood the neuron will fire, or inhibitory in that they lower the likelihood that the neuron will fire.

这些刺激信号可能是兴奋性的,会增加神经元产生神经冲动可能性,也可能是抑制性的,会降低神经元产生神经冲动的可能性

And what an agonist does is increases the effect of neurotransmitters, either by making more neurotransmitters or stopping the cleanup of neurotransmitters, or in some cases by faking a neurotransmitter, by mimicking its effects.

兴奋剂会增加神经递质的作用效果,有可能是通过释放更多的神经递质而实现,也可能是通过阻止神经递质的排出而实现,也有时候是通过伪造神经递质,通过模仿神经递质的效果来实现的
