"Dopamine is considered a neurotransmitter that is crucial for our ability to perceive rewards and to be motivated in our behavior."

When we discuss clinical psychology and depression we'll learn the extent to which neurotransmitter disorders are implicated in certain disorders like depression.

等我们探讨临床心理学以及抑郁症的时候,就会知道神经递质代谢障碍,对抑郁症这样的心理障碍的影响程度了

But in general, for each neurotransmitter that released it there would only be one population of receptors that's ready to receive it.

但总体说,每一种在此释放的神经递质,只能被一类受体接受

And one problem is that "For depression" is that there's too little of a neurotransmitter known as serotonin.

抑郁症的问题就在于,缺乏一种叫做血清素的神经递质

Because if it was a neurotransmitter activated ion channel, what would happen when the neurotransmitter bound here?

因为假如这是一个,神经递质激活的离子通道,当神经递质结合于此的时候,会发生些什么呢

So, that process happens fast but you also need this neurotransmitter release and activation to happen fast so that you can have rapid activity.

所以 电传递过程很快,但你仍需要神经递质的,快速释放和快速激活,以便使你快速活跃起来

In particular, they increase the amount of norepinephrine, a neurotransmitter that's responsible for just general arousal.

具体来说,安非他命会引起,去甲肾上腺素释放量的增加,去甲肾上腺素,是种负责一般性唤醒的神经递质

And one factor in Parkinson's is too little of a neurotransmitter known as dopamine.

引起帕金森症的一个病因,便是严重缺乏一种叫做多巴胺的神经递质

Neurotransmitter release is stimulated by the electrical activity that reaches the end of the axon.

到达轴突末梢的电流变化,刺激了神经递质的释放

This process, which is shown schematically here, as a vesicle fusing with the cell membrane and then dropping its neurotransmitter only happens when an action potential reaches the end of the axon.

这一过程 扼要地展示在这里,小泡同细胞膜融合,释放其神经递质,这只发生在动作电位抵达轴突末梢时

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

In some cells they're recycled, that is the cell is able to take up the neurotransmitter after it's released and restore it, but most often there are enzyme systems inside the pre-synaptic membrane where those neurotransmitters are synthesized.

在一些细胞中神经递质可以循环利用,这些细胞可以吸收,已经释放出的神经递质并重新储存起来,但更常见的是突触前膜中含有酶系统,在此合成神经递质
