is a study American scientist who comes to reveal: the phone does have an impact on our brain. Indeed, the electromagnetic waves emanating from the mobile good result in changes in the brain. Similarly, the cell phone emits electromagnetic waves more if the network is bad. The debate rages on this subject, based on the presence or absence of harmful effects of mobile phone use on the brain. Previous researchers have highlighted the link between the use of mobile and brain, but two competing conclusions about the harmfulness or otherwise of these effects. Studies by experts from major companies manufacturing and marketing of mobile phones, on the one hand, and by most independent experts, on the other hand, not all the same conclusions about the danger posed these electromagnetic waves on human health, including the brain. In the recent U.S. study, an observation of the effects of these waves on the human brain was performed. It showed that when the brain was exposed to a mobile phone, it produced more glucose in the area closest to the phone's antenna. The update of this evidence strengthens previous scientific findings proving that the waves affect the human body. While waiting to have a study that would decide finally between two opposing theories, the authorities and many medical professionals recommend avoiding prolonged exposure of brain cell phone and use thereof by the infants.
Using a mobile phone "active" brain
The emission of electromagnetic waves due to the use of a cell phone that does not stimulate the area near the unit. This
brain stimulation does not suggest a health risk.
Cell phones raise concerns among many users. So far, issues relating to their involvement in the development of brain tumors have been contradictory answers from scientists. While some studies claim the existence of a cause and effect, others show just the opposite. Last year, the Interphone study had found no increased risk of cancer for laptop users but it nevertheless emphasized that research should be pursued.
In this context, the work of U.S. researchers will not fail to relaunch the debate on the possible dangers of mobile phones. These doctors of the National Institute of Drug Addiction, Bethesda (Maryland) conducted a study whose results were recently published in the prestigious Journal of the American Medical Association (JAMA).
It appears that simply sticking a cell phone to the ear significantly increased brain activity. Specifically, the electromagnetic waves have an impact on the metabolism of a brain region without it being equally possible to conclude a real danger health of the user. To accomplish their work, these researchers have studied and recorded the brain responses of 47 patients to whom they placed on a cell phone ear for fifty minutes. Guinea pigs should not speak and no sound came out of the device which was placed in turn on their right and left ear. They had twice received an injection of fluodésoxyglucose (a tracer). The aim is to measure glucose metabolism in the brain, an important marker of brain activity, once with the laptop turned on (without sound) and this for fifty minutes and then with the phone off.
physicians were able to compare the relationship between glucose metabolic activity and the amplitude of the frequency of the electromagnetic signals emitted by the device. After they have seen images on the impact of mobile on glucose metabolism in the human brain.
The researchers found that use of fifty minutes of a phone increases glucose metabolism in a brain region located at the ear, so close to the antenna of the phone. Their findings are interesting because they discovered that this metabolism does not vary throughout the brain but only the area near the mobile phone, namely the orbitofrontal cortex and temporal pole. At this precise point, the metabolism of glucose was about 7% higher compared to the period during which the phone was off.
"These results show that the metabolism of the human brain is sensitive to the effects of magnetic waves lasting if exposed to these phones," observed the American researchers. A view shared by Dr Michael Desmurget, neurophysiologist and research director at Inserm. "This study will show that waves of Cell phones have many effects on glucose metabolism. According to the most likely hypothesis, this can be explained by an increase in the excitability of neurons. The latter being more excitable after being subjected to fifty minutes of waves, "says Michel Desmurget.
According to this expert, this is a new study showing that mobile stone have significant effects on brain activity. "Whether or not the laptop has carcinogenic effects will require further research before we can say that. Several studies are currently underway, including the United States. The results will Known for years to come, "he concludes.
