Thumb Typing Is Changing Our Brains

In short, when we use smartphones our brains show more activity in the parts associated with the thumb, but this reaction only happened in users of touchscreen phones.
The scientists studied “37 right-handed people, of whom 26 were touchscreen Smartphone users and 11 users of old cellphones.” They found that cortical brain activity in the area associated with thumb control was higher in the touchscreen users. This actually points to similar findings in violinists whose brains change as they get better at the instrument.
