All that texting is changing your brain.

A new study shows that the delicate, repetitive finger movements that people use on their smartphone’s touch screen result in a change in the brain’s sensory-processing area.

The findings suggest that a common, daily activity such as smartphone use could teach scientists about the details of brain plasticity, which is the ability of the neuronal networks to conform to changes in the body or the environment.

“Smartphones offer us an opportunity to understand how normal life shapes the brains of ordinary people,” said study co-author Arko Ghosh, a neuroscientist at University of Zurich in Switzerland.

The body’s entire surface is mapped out in a part of the brain called the somatosensory cortex, which receives signals from sensory receptors on the skin and other organs. So, for example, if you touch something with your fingertip, or if you bite your tongue, the region of the cortex that corresponds with those places in the body would receive the signal.

But these areas can adapt and become more sensitive when a particular part of the body is used frequently. For —> Read More Here
