Phone changes brain activity

If someone applies a cell phone to the ear and talks for 50 minutes or more, the activity of the nerve cell in the brain area closest to the antenna will change.

Fox News reported that scientists at the National Institutes of Health conducted a test to test the brain's response to electromagnetic fields caused by cell phone waves. They monitored activity in the brains of 47 volunteers with a CT scanner. They then asked all volunteers to listen to their cell phones for 50 minutes and then monitor their brain activity.

The results showed that glucose exchange activity (a sign of brain activity) in the most antagonistic brain region increased by 7%, but did not change in the rest of the brain.

Dr. Nora Volkow, the lead researcher, said that the researchers were surprised to find that the weak electromagnetic radiation of the phone could alter brain activity. However, she does not know whether this change is beneficial for the brain.

Some previous studies have indicated a link between mobile phone use and cancer risk. But a large-scale study by the World Health Organization indicates that the risk of cancer because of cell phone use is unclear.

Professor Patrick Haggard, a scientist at the University of London in England, commented that the results of the study are very interesting, because it sees the signal of mobile phones causing a direct impact on brain activity. . But the rate of glucose exchange also increases when people perform other behaviors, such as drinking alcohol.

" If future research confirms that cellular waves directly affect the metabolism of the brain, we have to find out if these effects can be harmful to health ," Haggard said. expression.
