Sometimes it is difficult to determine whether a particular animal is a true hibernator.

例如，熊很容易从眠中被唤醒。它们不是真正的眠。有时很难确定一种特定的是否是真正的眠。

And black bears, like most hibernators, don’t urinate or defecate the entire hibernation season.

黑熊和大多数眠者一样，在整个眠季节都不会小便或排便。

To find out how hibernators are able to do this, researchers turned their attention to those animal’s genomes.

为了眠是如何做到这一点的，研究人员将注意力转向了这些的基因组。

Understanding how hibernators deal with reduced blood flow could lead to better treatments for protecting the brain during a stroke.

了解眠者如何应对血流量减少可能会导致更好的治疗方法来保护中风期间的大脑。

Some animals that fall into a wintertime sleep are not true hibernators because they spend only apart of the cold season asleep.

一些进入季睡眠的不是真正的眠，因为它们只在寒冷季节的一部分时间睡觉。Bears，for example，can easily be awakened from their winter nap.Theyare not true hibernators。

So far, they’ve discovered that hibernation is controlled by genes that turn off and on in unique patterns throughout the year, fine-tuning the hibernator’s physiology and behavior.

到目前为止， 他们发现眠是由基因控制的，这些基因全年以独特的模式关闭和开启，从而微调眠者的生理和行为。
