Studies show how smartphone dependence changes the work of the brain
It’s no secret that millions of smartphone users can not do without them and several hours. A recent study conducted by scientists at the University of Seoul, led by Professor Neuroradiology Hyun Suk Seo, showed that prolonged use of the gadget leads to a chemical imbalance in the brain. Scientists have used magnetic resonance spectroscopy (MRS) to study chemical reactions in the brain in adolescents who are not parting with their smartphone.
Two groups were surveyed, which conditionally can be called “smart-independent” and “healthy” for 9 men and 10 women (average age 15.5 years) in each.
Standardized tests have helped scientists determine how serious dependence is on the smartphone, and how it affects the daily lives of their owners, from communication to sleep.
It was found that “smartphone-dependent” teens are more prone to depression, anxiety, sleep disorders and increased impulsivity. Using MRS, levels of gamma-aminobutyric acid (GABA), a neurotransmitter slowing brain signals, and glutamine, stimulating neurons, were measured.
Studies have shown that the ratio of these substances in dependent adolescents is higher than in healthy ones. The increased level of GABA causes drowsiness and anxiety, and the disturbed balance as a whole leads to a decrease in the ability to process information .
