【题目】 "What! You, too? I thought I was the only one." Have you ever said this to someone? If so, you may have ended up becoming friends with this person.

It seems that similarity often helps from friendships. The Greek philosopher (哲学家) Aristotle once said, "Some define (下定义) it (friendship) as a matter of similarity; they say that we love those who are like ourselves."

Now, there is some science behind this idea. Scientists from University of California said friends have similar brains, Scientific America reported.

The scientists invited 42 university students to take part in an experiment. Each student watched the same set of videos, which included a comedy, a debate (讨论) and a soccer match. At the same time, scientists scanned(扫描) their brains and recorded their brain activity.

Similar parts of their brains became active while watching the videos, especially parts that are connected with motivation (动力), learning and memory. According to their scans, friends who watched the same videos parts reacted in similar ways. However, people who weren't friends has different reactions to the same video parts.

Having close friends whose brain react like ours may be useful because it makes one's own value, opinions, and interests stronger, lead scientist Carolyn Parkinson told Business Insider.

But brain similarity is not the only thing that can result in friendship. Scientists from the University of Leipzig, Germany, found that friendship is also based on how physically close you are to someone. They did an experiment with first-year college students who met in class for the first time. Is this experiment, students who sat in neighboring seats were more likely to become friends.
