微笑是如何控制我们所有人的

Certainly what we see greatly influences when we smile, but it is not necessary. We need no visual feedback to smile. Darwin discovered that those who are born blind will still smile appropriately during a conversation. You can smile when all alone, but smiling is definitely enhanced by socializing; it happens six times more frequently in social settings.

当然，当我们微笑时我们看到极大的影响，但这是不必要的。我们不需要视觉反馈去微笑。达尔文发现，那些天生的盲人在一场交谈中依然会微笑得体。当独自一人时，你可以微笑，但是微笑绝对是通过社交来增强的;它在社会环境中更频繁，是独自一人时候的六倍频率。

Some of the complexities of smiling can be appreciated by examining those who can't do it normally. People who have suffered brain damage may not be able to smile when asked to but will still involuntarily smile at a joke. Conversely, patients suffering from Parkinson's disease, a disease of dopamine-containing neurons in the brain, may be able to turn up the corners of the mouth when asked to smile but after getting a joke may lack the ability to smile as a natural, automatic response. Patients who have had a stroke leading to paralysis of half of their face lack an ability to voluntarily move one side of their face. They show a crooked smile when asked to grin but a normal smile on hearing a joke, indicating intact nerve pathways beyond their conscious control. Clearly, the pathways for smiling are quite elaborate, with both unconscious and conscious connections that receive inputs from different parts of the brain.
