Smartphone use is changing our brains

The scientists used something called electroencephalography (EEG) to measure brain activity. They found distinct differences between smartphone users and people who used 'conventional' cellphones. Smartphone users had more attuned fingers and thumbs, based on their EEG readings. Of the 37 volunteers, 26 were touchscreen smartphone users while 11 used 'old-fashioned' mobile phones. 

 

The EEG readings looked at the electrical messages sent back and forth between the brain and the hands via nerves. Multiple electrodes placed on the volunteer's scalp recorded these exchanges about sensation.

 
From this, the researchers were able to build up a picture or map of how much brain tissue is devoted to a given body region. The results revealed discernable differences between touchscreen smartphone users and people with conventional cellphones. Smartphone users had bigger EEG brain activity measurements in response to mechanical touch on the thumb, index and middle fingers.
 
And this appeared to be linked to how often they used their touchscreens - the more frequent, the greater the EEG response. The researchers say their findings, published in the journal Current Biology, make sense given that the brain is malleable and can be moulded by experience.

I think that similar findings- changes in specific brain structures associated with particular tasks - could be found for other defined activities and there is no harm, just adaptation Reply
