City México.- According to a study published in the journal Current Biology, the use of the touch screens on smart phones change the way the Thumbs and brain work together, because this activity is capable of producing greater brain activity.
The advent of touch screens in countless devices such on smartphones, have made users to develop new skills with fingers , especially the thumbs, which are the employees into a “smartphone”.
Arko Professor Ghosh led a team of Swiss Universities of Zurich and Fribourg, realizing that the obsession with the use of smartphones could give the daily opportunity to analyze brain plasticity and understand how it shapes everyday life.
The digital technology we use in our daily life molds the sensory processing of our brains a proportion that has surprised us, “said the doctor.
Each region of the body has a specific area in the emotional center of the brain , where your information is processed, which is flexible and can change.
So, the researchers studied the activation of the sensorimotor cortex, which is activated by the movement of the fingers . To do this they performed electroencephalograms measuring the activity of cortical regions of the brain in 37 right-handed people.
With the EEG recorded the brain response when users smartphone touching the screen with the thumb, index and middle , to then compare it with that of people still using old traditional mobile keypads.
The data revealed that electrical activity in the brain of users of “smartphone” increased by touching the tips of three fingers above.
Also, the amount cortex activity brain associated with the thumb and forefinger was directly proportional to the amount of time the smartphone is used.
Therefore, the study authors believe that the sensory processing of the cortex in our brains “is continuously remodeled by the personal digital technology “.
