Today’s manufactures of smartphones have shifted the market to the Touch oriented. And mostly user preferred thumbs to operate it, although we never operate keypad phones with fingers (Every one has its own taste and likeness, We are talking on a large scale). The latest study related to this scenario is coming from Dailysience which is somehow beneficial for us. We come to know that smartphone use has changed the way thumbs and brains operate together, with brain signals becoming supercharged when the thumbs and fingertips are engaged.
“I was really surprised by the scale of the changes introduced by the use of smartphones,” Dr. Arko Ghosh, a neuroscientist at the University of Zurich and ETH Zurich in Switzerland, said. “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.”
In more explanation Dr. Ghosh said that,
“I think first we must appreciate how common personal digital devices are and how densely people use them. What this means for us neuroscientists is that the digital history, we carry in our pockets has an enormous amount of information on how we use our fingertips (and more).”
To implement it and see the real statistics, the team selects some smartphone users and attached them to the EEG machines in order monitor the activities of the brain. And this thing comes in the right way as they were thinking, whenever a user press its thumb the cortex activity in the brain was directly proportional to level of phone activity. Thumb-to-brain responsivity became enhanced, and the more a volunteer engaged with a smartphone the more elevated the cortical activity.
