Your Elder is suffering from a form of spongiform encephalopathy.

你的长老患的是一种海绵状的脑病。

Your neurology department loaned me a culture of prions for my research on bovine spongiform encephalopathy.

你们神部门借了朊病毒培协助牛海绵状脑病的研究。

In particular, Prion disease creates holes in the brain, giving it a spongiform appearance and ultimately causing death.

特别是，朊病毒病会在大脑中形成一个个洞，使其看起像海绵一样，最终导致死亡。
