The main excitatory neurotransmitter in the brain is glutamate.

脑部主要的兴奋性神经递质为谷氨酸。

To do that, they needed to test how the filopodia responded to glutamate, the brain's main excitatory neurotransmitter.

要做到这一点，他们需要测试树突丝对谷氨酸的反应，谷氨酸也就大脑主要的兴奋性神经递质。

Vocal variation adds excitement and emphasis to speech.

声音的变化增加了讲话的兴奋性和强调性。

Because it slows you down and relaxes you, and it decreases more excitatory neurotransmitters.

因为它让你减缓速度、放，并减少更多的兴奋性神经递质。

So the release, of these excitatory amino acids occurs.

所以这些兴奋性氨基酸的释放就发生了。

This reduces the heart's excitability and suppresses reentrant tachycardia.

这降脏的兴奋性和抑制折返性快速性律失常。

The effect this has on excitability of myocytes, however, is complex.

然而，这对肌细胞兴奋性的影杂的。

It's all these inhibitory and excitatory messages that are forming memories.

正这些抑制性和兴奋性的信息在形成记忆。

But there are likewise going to be a number of different ones that are excitatory.

但同样也会有许多不同的兴奋性神经递质。

Alternatively, it is possible that ketamine exerts its effects by decreasing excitation in regions whose activity promotes depressive-like phenotypes.

另一种可能，氯胺酮通过降那些活动会促进类似抑郁表型区域的兴奋性来发挥其作用。

While initial changes seem to increase myocyte excitability; further rise of potassium has the OPPOSITE effect.

初始变化可能增加肌细胞的兴奋性，但钾进一步升高却具有相反的作用。

The result is a reduced excitability or responsiveness of the neurons and muscles in the heart.

这导致脏神经元和肌肉的兴奋性或反应性降。

In addition to that, these same dopaminergic neurons also exert inhibitory effects on the excitatory cholinergic neurons in the striatum.

除此之外，多巴胺能神经元也有同样的抑制作用纹状体的兴奋性胆碱能神经元。

REPORTER 2: Autopsy results show that Bolick died of acute exhaustion mania, which is also known as excited delirium syndrome.

记者2：尸检结果显示， 博利克死于急性疲惫性躁狂，即所谓的兴奋性谵妄综合征。

So, NMDA receptors belong to the family of ionotropic glutamate receptors, which mediate most of the excitatory synaptic transmission in the brain.

因此，NMDA受体属于离子型谷氨酸受体家族，它介导大脑中大部分的兴奋性突触传递。

And so depending on the amount of excitatory and inhibitory that we have, it's either going to fire or it's not going to fire.

因此， 根据我们拥有的兴奋性和抑制性信号的多少，神经元要么会放电， 要么不会放电。

Those messages can either be excitatory, so yes, you need to keep that message going or inhibitory, no you need to stop the message right here.

这些信息可能兴奋性的，意味着你需要继续传递该信息； 也可能抑制性的，表示需要在此停止传递。

Ultimately this imbalance between inhibitory and excitatory activities leads to the manifestation of typical clinical symptoms that include resting tremor, rigidity, postural instability, and slowed movement.

最终，抑制性和兴奋性之间的不平衡导致了这种表现典型的临床症状包括静止性震颤、僵硬、姿势不稳，减缓了行动。

Now, as you may know, the binding of glutamate to the NMDA receptor results in an influx of extracellular calcium, which controls membrane excitability and synaptic transmission.

现在，如你所知，谷氨酸与NMDA受体的结合导致内流细胞外钙，控制膜的兴奋性和突触传递。

Some researchers suspect that this deficiency takes the breaks off glutamates excitery activity thus stimulating things like repetitive behavior documents money and then his colleagues produced evidence supporting this idea.

一些研究人员怀疑这种缺乏会解除谷氨酸兴奋性活动的刹车，从而刺激重行为、刻板行为等。随后，他的同事提供了支持这一观点的证据。
