Recently Swiss researchers found out that smartphones are actually changing how our fingers work. By how much you use your smartphone you brain cortex associated with your thumb and index finger works better and faster. But by time if you don’t use your smartphone or stop messaging for a while it will fade away. They suggest that repetitive use of smartphones will alter your sensory process leading to your brain feeling and operating your fingers in a different way. Fortunately or not this is happening and it shows that not just professional skills that require more hand dexterity such as music is changing how your fingers work together.
