Their study involved a group of proteins called cadherins, which help your cells stick together.

他们研究涉及一组称为钙粘质，可帮助您细胞粘在一起。

But what they found was the opposite: mice that were producing more cadherin showed less tendency toward cocaine addiction.

但他们发现恰恰相反：产生更多钙粘小鼠表现出对可卡成瘾倾向较小。

In this study, researchers genetically engineered mice to produce extra cadherin, which they predicted would mean more stable synapses, stronger memories, and more tendency towards addiction.

在项研究中， 研究人员对小鼠进行基改造以产生额外钙粘，他们预测味着更稳定突触、更强记忆力和更容易上瘾倾向。

But the mice with extra cadherin spent the time in both rooms. And the researchers took this to mean the genetically-engineered mice weren’t forming strong memories related to addiction.

但是具有额外钙粘小鼠在两个房间都呆了。研究人员认为味着基工程小鼠没有形成与成瘾相关强烈记忆。

Our synapses need to get stronger and weaker, or reform completely for our memories to work properly, so flooding a human brain with extra cadherins isn’t something we would want to do.

我们突触需要变得更强和更弱，或者彻底改造我们记忆才能正常工作， 所以用额外钙粘淹没人脑并不是我们想要做事情。
