Touchscreen, use them changes the brain. For the better – The Republic

THE BRAIN human is routinely modified by the use of smartphones and tablets, in particular by the rapid and frequent movement of the fingers on the screen. E ‘as shown by a study of the Institute of Neuroinformatics, University of Zurich and ETH Zurich that investigated the impact that the finger dexterity of users of touchscreen has on the brain.

Each region of the body, in fact, a match with an area of ​​the sensorimotor cortex. In the case of violin, for example, the area representing the finger that drive the tool is greater than other people. The researchers then studied the cortical brain activity triggered by finger movements in 37 people, of whom 26 were users of to uchscreen smartphones and 11 of traditional mobile phones. Via electroencephalography recorded the movements of the thumb, index and middle fingers, revealing that the cortical representation differed significantly between the two groups.

“The digital technology we use daily plasma sensory processing in the brain to a surprising extent,” says one of the authors, Arko Ghosh. Cortical activity have also noted, depends on the frequency of use of smartphones more had been used in the previous ten days, the greater was the signal in the brain, in particular in the area corresponding to the thumb. While it was not relevant as time smartphone users had possessed and made use of the device
