原文: Baby, you make me happy

No, that's not the latest title to a pop song. It's just a fact. Researchers at the University of Oxford in England have discovered that merely looking at a baby's face triggers a part of our brain associated with rewards. So basically, one look and we're happy. Study participants didn't have the same reaction when they looked at other adults. Something about babies causes adult to respond positively with nurturing, caring thoughts.

The results of this study may hold clues to postpartum depression. It's possible that chemical changes during pregnancy or labor and delivery could alter the brain's ability to respond in its instinctive way.

译文: 宝贝，你让我快乐

      不，这不是一首流行音乐的最新歌名。这仅是个事实。英国牛津大学的研究人员已经发现，仅仅是看着婴儿的脸就可以刺激我们大脑中关于获得回报的神经。所以基本上来说，只要看一下婴儿，我们就会快乐。而对着大人时，该研究的参与者们却不会产生这种感觉。关于婴儿的东西会使成年人产生积极的反应，想要培养和照顾婴儿。 

    此次研究的结果可能会提供有关产后忧郁症的线索。在怀孕或者分娩期间的化学变化会改变大脑的本能反应能力，这种现象是可能的。
