爱真是个好东西！

A recent study used functional magnetic resonance imaging to see how love affects the brain. Its calculations of love has attracted plenty of attention.

最新一项研究利用机能性磁共振成像技术来观察爱情如何影响大脑。其中爱的计算得到了广泛的关注。

For example, the time taken to "fall in love" clocks in at about one-fifth of a second, not the six months of romantic dinners and sharing secrets some might expect.

例如，坠入爱河的时间大约持续五分之一秒，这可是持续六个月的浪漫晚餐或分享秘密都可能得不到的感觉。

Also, 12 areas of the brain work together during the love process, releasing euphoria-inducing chemicals like dopamine, oxytocin, adrenaline and vasopressin. Love's high is similar to cocaine's rush.

还有，恋爱的时候大脑的12个区域一起运转，释放出一些兴奋诱导素例如多巴胺，催产素，肾上腺素或加压素等化学物质。

Love influences sophisticated intellectual processes of the brain too. When a person feels in love, their mental representation, metaphors and even body image are also affected.

爱也影响到大脑复杂的智力过程。当人坠入爱河时，其心理表征，具体表现，甚至身体意象都会受到影响。

Researchers from Syracuse University, West Virginia University and the Geneva University Psychiatric Center retrospectively reviewed pertinent neuroimaging literature. They published their findings in a recent issue of the Journal of Sexual Medicine.

来自锡拉库扎大学，西弗吉尼亚大学和日内瓦大学精神病学中心的研究人员回顾了相关的神经影像学文献。他们在最近的性医学期刊中发表了其调查结果。

Overall, they found, love is really good for you.

总而言之，他们发现，爱的确对人有益。

Couples who had just fallen in love had significantly higher levels of nerve growth factor, or NGF. NGF is crucial to the survival of sympathetic and sensory neurons. Some believe NGF can reduce neural degeneration. Not a bad side effect.

刚刚坠入情网的恋人明显有较高水平的神经生长因子。神经生长因子对交感神经元和感觉神经元的存活至关重要。有的人认为神经生长因子可减少神经变异。可见这真不是个坏的副作用。

Just as love is diverse, the part of the brain affected is also different.

正如爱是多样的，大脑被影响的部分也是不同的。

Unconditional love, the type often seen between a mother and child, lights up the common and different brain areas, including the middle of the brain.

经常在母亲和孩子之间产生的那种无条件的爱可激活其共同的和不同的大脑区域，包括大脑的中部区域。

Not surprisingly, passionate love fires the reward part of the brain, but it also affects the higher-order cognitive function seen in body image.

并不令人吃惊的是，激情之爱可激发大脑获得报酬而产生愉悦感的区域，它同时也影响到身体意象的高阶认知功能。

A follow-up study about the speed of love in the human brain is expected to follow soon.

后续的一项关于大脑爱的速度的研究，预计很快就会推出。
