If bubbles of sodium vapour formed in the coolant, that damping effect would diminish, risking a dangerous feedback loop of rising temperatures and growing power output.

如果在冷却剂中形成钠蒸汽的气泡，这种阻尼效应将会减弱，冒着温度上升和功率输出增加的危险反馈回路的风险。

And this was possible because the brain circuits-different parts of the brain responsible for different functions-start talking to each other in new ways that created enduring-meaning long-lasting-changes.

这是可能的，因为大脑回路——大脑里负责同功能的同部位——开始以新的方式互相交流，这种方式能够产生持久的——即可以延续很长时间——改变。

The general message from the reward circuit is " Do what feels good! "

上从奖励回路发出的信息就是：去做那些感觉棒的事吧。

The instability is a positive feedback loop.

这种稳定性是种正反馈回路。

Now, importantly, from the perspective of PTSD, stress has very different effects on declarative and non-declarative memories and the brain circuits and regions supporting them.

In practice, confidence is distributed very lumpily and is also susceptible to feedback loops.

在实践中，自信的分布均衡，而且也容易受到反馈回路的影响。

Looks like you're doing work in quantum loop corrections. Keen observation. Good-bye.

For the new application, the scientists added links to the circuit made of carbon nanotubes.

而对于这样一款新应用程序，科学家们在碳纳米管制成的电线回路加上了链接。

You activate particular neural circuits associated with habits every time you repeat them.

每当你重复习惯时，你就会激活与之相关的特定神经回路。

It all works as a feedback loop, and it works best when we're prepared.

这一切就像一个反馈回路，当我们有所准备的时候效果最好。

Some researchers argue that doodling activates the brain's so-called default circuit — essentially, the areas of the brain responsible for maintaining a baseline level of activity in the absence of other stimuli.

一些研究院认为涂画会激活人脑中所谓的默认回路——也就是在没有其他刺激情况下，大脑中负责保持活动的区域。

On top of our physiological features: The brain, which is just like a complicated circuit of nerves that manipulate pitch and emotion and inflection in the voice.

最重要的生理特征是：大脑，它就像一个复杂的神经回路，控制着声音的音调、情绪和变化。

And then we can use that to figure out how to repair and then try to induce that in a brain like a human to see if we can repair those circuits.

接着，我们借此研究如何修复口吃问题，并试图在类似人脑的模型中找到修复脑回路的方法。

What this means is once we have a new word for a color, there's a feedback loop in the brain and this exaggerates the differences between those colors, especially at the border areas between them.

这意味着一旦我们有了一个颜色的新词，大脑中就会有一个反馈回路，这会夸大这些颜色之间的差异，尤其是在它们之间的边界区域。

The frontier is now not so much at the animal behavior level but actually getting inside the brains of these animals and trying to find these sensing cells and connecting them to the neural circuitry.

现在的前沿问题是在动物行为层面，而是实际进入这些动物的大脑，试图找到这些感应细胞并将它们与神经回路连接起来。

Symptoms of Schizophrenia appear when one of the neural circuit situated in the midbrain, called Substantia nigra, overproduce neurotransmitter called Dopamine and disrupts the balance between secretion of Dopamine and Acetylcholine.

当位于中脑的黑质神经回路产生过量多巴胺，并破坏多巴胺和乙酰胆碱分泌之间的平衡时，就会出现精神分裂症的症状。

And while it might be frustrating to scientists that we haven't been able to build artificial brain circuits, it also means that humans aren't completely replaceable... yet.

虽然科学家们可能会对我们还无法构建人工脑回路感到沮丧，但这也意味着人类还能完全被取代......。

" Dopamine is associated with reward circuitry and goal-directed behavior, so when you set short-term goals with rewards attached to them, it can positively shape your productivity, " he says.

“多巴胺与奖励回路和目标导向的行为有关，所以当你设定短期目标并附带奖励时，它会积极地塑造你的生产力，”他说。

Another concern is that GLP-1 agonists might be too good at dampening the pleasure and reward pathways, to the point where they would cause disruptions in mood or motivation.

另一个担心是 GLP-1 激动剂可能过于擅长抑制愉悦和奖励回路，以致于会导致会破坏情绪或动机。
