Once attraction is confirmed, your bloodstream is flooded with norepinephrine, activating your fight or flight system.

一旦吸引力被确认，你的血液和肾上素一起沸腾，激发你的“战斗或逃跑”系统。

Whether you're awake or asleep, norepinephrine helps you remember things.

无论清醒状态下还是着了，甲肾上素都能帮助人们记住各种事情。

First, it optimizes the levels of neurotransmitters like serotonin, norepinephrine, and dopamine.

首先，它能优化神经递质水平，如血清素、甲肾上素和多巴胺。

When you fall asleep though, your norepinephrine levels drop.

当你入，甲肾上素水平下降。

Your adrenal gland releases the stress hormones cortisol, epinephrine, also known as adrenaline, and norepinephrine.

你的肾上放压力荷尔蒙皮质醇，肾上素，以及甲肾上素。

And releases epinephrine and norepinephrine into the blood making your heart pump faster.

并向血液中放肾上素和降肾上素使你的心跳加速。

You've probably heard of a couple of these neurotransmitters—serotonin and norepinephrine.

或许你可能听过几种神经递质介质——5-羟色胺与降肾上素。

Well, exercise releases an important blend of mood altering hormones including dopamine, serotonin and norepinephrine.

通过锻炼，人体放一些重要的情绪调节激素，包括多巴胺、血清素和降肾上素。

They lose their sensitivity to serotonin and norepinephrine. Which leads to...? Impaired cognitive function.

失对5 羟色胺和正肾上素的敏感性 那就引起认知功能受损。

Once it hits your bloodstream, it targets three major neurotransmitters — serotonin, dopamine, and norepinephrine.

一旦它进入你的血液，它就瞄准三种主要的神经递质——血清素、多巴胺和甲肾上素。

Aside from its positive effects on dopamine, exercise also elevates levels of norepinephrine and serotonin.

除了可以增加多巴胺外，锻炼还能提高体内的甲肾上素以及 5-羟色胺水平。

Tyrosine is needed to synthesize dopamine and norepinephrine, and tryptophan is needed to synthesize the neurotransmitter serotonin.

酪氨酸是合成多巴胺、甲肾上素所必须的；色氨酸是合成神经递质血清素所必须的。

So, the preganglionic fiber releases ACh, and the postganglionic releases norepinephrine.

所以节前神经纤维放 ACh，节后神经纤维放甲肾上素。

And disturbances in norepinephrine transmission is thought to also be a key component in depression.

甲肾上素传递的紊乱也被认为是抑郁症的关键诱因。

This mood-depressing drug also reduced brain levels of norepinephrine, dopamine, and serotonin.

这种抑制情绪的药物还能降低大脑中甲肾上素、多巴胺和 5-羟色胺的水平。

This one's called norepinephrine. And it is always norepinephrine that's released from postganglionic fibers in the sympathetic nervous system.

这个叫做甲肾上素。交感神经系统节后纤维放的永远是甲肾上素。

Adderall also causes the release of norepinephrine, which activates the sympathetic nervous system, initiating your fight-or-flight response.

Adderall 还导致甲肾上素的放，从而激活交感神经系统，引发你的“战或逃”反应。

These three are all technically monoamines but norepinephrine and dopamine are classified as catecholamines.

严格说来，这三种激素都属于单胺，但甲肾上素和多巴胺也被归为儿茶酚胺。

And, interestingly, Noradrenaline, also called norepinephrine, is one of the neurotransmitters released when you are exposed to the cold.

有趣的是，甲肾上素（又名 norepinephrine）正是大脑在寒冷环境中分泌的一种神经递质。

Higher levels of norepinephrine also apparently causes a tendency towards anger and aggression.

高水平的甲肾上素能显著导致愤怒和攻击的倾向。
