Sorry to disappoint, it's not all tarantula, scorpion, snakes, and rat brain.

抱歉让你失望了，不全是狼蛛、蝎子、蛇和鼠脑。

They are wiring their organoids into rats brains and not only that.

他们正在将他们的类器官连接到老鼠的大脑中，不仅如此。

The organoids grew so that they eventually occupied a third of the hemisphere of the rat's brain where they were implanted.

类器官不断生长，最终占据了被植入类器官的老鼠大脑半球的三分之一。

She told the French news agency AFP the research suggests that rat brains may be more complex and flexible than once thought.

她在接受法新社采访时表示，该研究表明，鼠类的大脑可能比我们之前想的要更复杂、更灵活。

To examine how the idea might be useful for studying human health, scientists transplanted organoids into both sides of a rat's brain.

为了检验这一想法对研究人类健康是否有用，科学家将类器官移植到老鼠大脑的两侧。

And it supported a rat study in which rat brains cooled a bit when the animals yawned.

它还支持了一项大鼠研究，在该研究中，当动物打哈欠时，大鼠的大脑会稍微冷却。

A chemical compound was used to destroy dopamine neurons in rats' brains, and this destroyed the rat's capacity for motivation or " wanting."

他们用一种化合物来破坏老鼠大脑中的多巴胺神经元，这就破坏了老鼠的动力和渴望的能力。

The next step, Arlotta adds, will be to work out how individual human neurons — not just fully developed organoids — are integrated into the rat brain.

Arlotta 补充说道，下一步将是研究个体的人类神经元——而不仅仅是完全发育的类器官——是如何融合到大鼠的大脑中的。

When a rat gets infected by eating cat feces, the parasite changes chemical levels in the rat's brain, making it less cautious around the hungry felines, maybe even attracted to them.

当老鼠吃猫屎被感染，这种寄生虫会 改变鼠脑的化学平衡，使牠们对於饥饿的猫 更不知危险，甚至使老鼠想接近猫。

Human brain cells mature much more slowly than rat cells, so the researchers had to wait for more than six months for the organoids to become fully integrated into the rat brains.

人类的大脑细胞成熟要比大鼠的细胞慢得多，所以研究人员等待了6个多月，才能让类器官完全融入老鼠的大脑。
