It predicts that the best timing is when the conditioned stimulus, which is the signal, comes before the unconditioned stimulus, which is what you have to prepare for.

它预测，最佳的时机,莫过于作为信号的条件刺激，出现在需要你做准备的，非条件刺激之前。

There are sensory neurons, which take information from the world so as you see me, for instance, there are neurons firing from your retina sending signals to your brain.

感觉神经元,负责收集外界信息,比如,当你看到我的时候,视网膜上的神经元会产生神经冲动,将刺激信号传递到你的大脑

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
