SMARTPHONES CHANGE BRAIN AND THUMB INTERACTION

摘要

Typing text messages, scrolling Web pages and checking your email on your smartphone could be changing the way your thumbs and brain interact. That's according to researchers from the University of Zurich, ETH Zurich and University of Fribourg. Dr. Arko Ghosh of the University of Zurich and ETH Zurich led the research that involved using electroencephalography (EEG) to measure the cortical brain activity in 37 right-handed people. The study, published in the Cell Press journal Current Biology in December 2014, included 26 touchscreen smartphone users and 11 users of old-fashioned cellphones. Subjects wore an EEG cap with 62 electrodes to record how the brain processed touch from their thumb, forefinger and middle finger. Researchers then compared brain activity with the commands recorded by each individual's phone logs.
