Using smartphones profoundly changes the way the thumb and brain work together, a new study finds.
The electrical activity in a smartphone user’s brain spikes when their fingertips are touched, in comparison to an old-school phone user, the researchers found.
And the more people use their smartphones, the greater the spike in activity across the cortex.
Dr. Arko Ghosh, who led the study, said:
“I was really surprised by the scale of the changes introduced by the use of smartphones.
I was also struck by how much of the inter-individual variations in the fingertip-associated brain signals could be simply explained by evaluating the smartphone logs.”
