The use of touchscreens of smartphones changes the way Thumbs and brain work together, resulting in increased brain activity, according to a study published today in the journal Current Biology.
The appearance of the touchscreens in countless devices, eg smartphones, have led users to develop new skills with fingers , especially the thumbs, which are the employees in an smartphone .
Arko Professor Ghosh led a team of Swiss Universities of Zurich and Fribourg, realizing that the obsession with the use of the smartphone could give them the opportunity to analyze the daily brain plasticity and understand how everyday life shapes it.
“Digital technology we use in our daily life molds the sensory processing of our brains in a proportion that surprised us,” said the doctor.
Each region of the body has a specific area on the emotional center of the brain where information is processed, which is flexible and may change.
Thus, researchers studied the activation of the sensorimotor cortex, which is activated by the movement of the fingers. To do EEGs performed measuring the activity of cortical regions of the brain in 37 right-handed people.
Thanks to electroencephalogram They recorded brain response when smartphone users touching the screen with your thumb, index and middle, to then compare it to the people who continue to use mobile old traditional keyboards.
The data revealed that the electrical activity in the brain users “smartphone” increased by touching the tips of three fingers above.
Furthermore, the amount of activity of the cerebral cortex associated thumb and forefinger was directly proportional to the amount of time that was used smartphone.
Therefore, the study authors consider sensory processing in the brain cortex “is continuously remodeled by personal digital technology.”
