Swiping fingers across a smartphone screen can make the brain more sensitive to the touch of the finger tips, a new study suggests.

The study, published in Current Biology this week, shows that brain response to thumb stimulation is partly explained by how often people use their smartphones, reports the Washington Post.

“I was really surprised by the scale of the changes introduced by the use of smartphones,” said Arko Ghosh, one of the study’s authors from the Institute of Neuroinformatics at the University of Zurich.

Researchers recorded brain activity when people touched their thumbs, index and middle fingers to a mechanical object. Smartphone users broadcasted increased activity compared to non-smartphone users, and the activity was boosted the more people used their devices.
