The impact of smartphone thumbing on your brain

Almost like a new drug, our addiction to using our smartphones is having a profound effect on our brains. Whether we’re texting, posting on Facebook, or playing Angry Birds, the way we’re repetitively using our fingers and thumbs on the smooth surface of a touch screen is causing certain areas of our brains to become bigger. In other words, we’re experiencing heightened brain activity that rewires sensory processing when our fingertips and thumbs are touched, a phenomenon known as “brain plasticity” in which the brain adapts to learning new things.
