The brains of people shown images of their lovers react similarly to those of drug addicts, a US experiment found. 美国一项科学实验发现，人脑对爱人照片的反应和吸毒上瘾时的反应相似。 Researchers looked at magneticresonanceimages of the brains of 10 women and seven men who claimed to be deeply in love. 科研人员研究了10名女性和7名男性的大脑核磁共振影像。参与实验者都声称自己正在热恋中。 The length of their relationships ranged from one month to less than two years. Participants were shown photographs of their beloved, and photos of a similar-looking person. 被研究者的恋爱时间介于一个月至两年间。科研人员向他们出示了其爱人的照片和其他长相相似于其爱人的照片。 The brains of the smitten participants reacted to photos of their sweethearts, producing emotional responses in the same parts of the brain normally involved with motivationand reward. 参与实验者在看到爱人的照片时大脑所产生的情感反应与其获奖时所表现出的反应是在同一区域。 "Intensepassionatelove uses the same system in the brain that gets activated when a person is addicted to drugs," said study co-author Arthur Aron, a psychologistat the State University. In other words, you start to crave the person you're in love with like a drug, the researchers said. |
