Your smartphone is changing the way your fingers work

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.
