为什么我们被挠痒痒时会笑?

挠痒痒是一个非常严肃的话题，克里斯。科学家们对此非常重视。最近，科学家们用核磁共振扫描仪对30名志愿者进行了研究，试图找到这种挠痒现象的根本原因，以及为什么我们觉得它如此搞笑和有趣。这与我们有关，我们没有预料到，我们没有预测到它会发生，我们不确定它会有什么感觉或者别人会怎么挠我们。人们在被挠痒痒或被讲笑话时接受核磁共振扫描结果显示，罗兰底盖，大脑中与面部运动和情绪反应有关的区域，在被挠痒痒和讲笑话时都活跃起来。但是当人们的脚被挠痒痒的时候大脑中有一个额外的区域会被激活当他们的脚从扫描仪中伸出来的时候那就是下丘脑，这很有趣。下丘脑参与调节我们对饥饿、疲劳和体温的感觉，它也参与逃跑或战斗反应。所以，如果你害怕，你可能会想和别人打架或逃跑。现在，节目制作人凯特·兰布尔，如果我威胁要逗她显然，如果她男朋友真的逗她，她会狠狠地揍那个逗她的人。所以，她似乎肯定会通过挠痒痒来激活她的战斗或逃跑反应。 So yeah, tickling seems to invoke these feelings in people and we're trying to understand. Scientists are trying to understand a little bit more about what happens in tickling. It seems to be an innate response laughing to tickling. So, new born babies, if they're tickled by a parent with a very straight face on, they will still start giggling and laughing away. So, it's something that we have evolved to do and we're still trying to understand it exactly.
