Your smartphone is changing more than just your habits，it's changing the way your hands work, too. Swiss researchers have discovered that activity in the brain's cortex associated with index fingers and thumbs is enhanced directly
in proportion to how often you use your phone's touchscreen. That area of your mind will light up if you message your friends all week, but it'll fade the longer you spend away from your device. People with basic cellphones don't see this, according to the
scientists. This suggests that repetitive smartphone use is altering your sensory processing, and that your brain is perceiving your digits in a different way. Whether or not that's a good thing is still up in the air, but it shows that you don't have to be
in a profession driven by hand dexterity (such as music) to see a shift in how your brain and fingers work together.
你的手机改变的不仅仅是你的习惯，它还改变着你手的工作方式。Swiss的研究人员发现，大脑和你的手指有关的皮质部分正在被加强，这和你的触摸手机屏幕的频率成正比。你的思考的相关区域会被激活在你和你的朋友一整天频繁联系时候，但是这个活跃程度会褪去如果你的慢慢不用你的手机。根据科学家的研究，使用功能机的人没有这样的区别。研究还发现，频繁地使用手机改变着你身体用于感知周围数据的传感器的方式。这是不是好事还是未知数，但着意味着你能轻松的让大脑和手指一起工作而不用经过专业的训练。
