They were inspired by questions from animal welfare committees at universities about whether mice were really enjoying wheel-running, an activity used in all sorts of studies, or were instead like bears pacing in a cage, stressed and neurotic. Would they run on a wheel if they were free?
他们的灵感来自一些大学的动物福利委员会所提出的问题。这些委员会质疑小鼠是否真的喜欢在轮子上跑步——所有研究都会用到这个活动,或者还是像在笼子里踱步的熊那样,出于压力和紧张。如果处于自由状态,它们还会在轮子上跑步吗?
Now there is no doubt. Mice came to the wheels like human beings to a health club holding a spring membership sale. They made the wheels spin. They hopped on, hopped off and hopped back on.
目前,这一点毫无疑问。到跑轮上跑步的小鼠,就像来到正在举行春季促销的健身俱乐部的人类一样。他们开始让轮子转动。它们跳上去、跳下来,然后再跳上去。
"When I saw the first mice, I was extremely happy," said Johanna H. Meijer at Leiden University Medical Center in the Netherlands. "I had to laugh about the results, but at the same time, I take it very seriously. It's funny, and it's important at the same time."
“当我看见第一只小鼠时,我非常高兴,”荷兰莱顿大学医学中心(Leiden University Medical Center)的约翰娜·H·梅杰(Johanna H. Meijer)说。“这些结果不能不让我觉得可笑,但同时,我也会认真对待它。这很有趣,同时也很重要。”
