Cell phone use stimulates brain activity

We all know that using the cell phone will make the brain worse. "Mr. Skerrett, this is the office of Dr. LeWine, do you have time to talk about the results of the test" or "Dad, the children are planning to go to Casey 's house after dancing." As a result of my research, I wanted to know not only the information provided by the phone, but also the energy emitted from the phone itself.

In short, this is research. Dr. Nora Volkow and colleagues recruited 47 volunteers to measure brain activities twice with a PET scanner. Both volunteers are connecting their mobile phones to their respective ears. In one measurement, both phones were turned off. On another phone, the phone was on but muted, so the volunteer did not know that it turned on; the others were canceled. Each meeting lasts about an hour. When scanning, you can see that the brain is using glucose (blood glucose) slightly when you turn on the phone, but only in the brain near the antenna.

This is an elegant study. Researchers do their best to predict the cause of the error. They used one control (two phones are turned off) to compare the effect of 'live' phones. They use the mobile phone for each ear, open it once, and turn it off once to see if the effect is placed. They mute open phones to eliminate the activation of the brain by the possibility of listening to the sound coming from the phone speaker. Therefore, the results are actual, not artifacts or measurement errors.

What does this brain activation mean? No one knows. As Dr. Volkow told the NPR, "I can not say whether their [cell phone] increases glucose metabolism or whether it is beneficial or not"

Of course, the biggest concern is cancer of the brain, not activation of the brain. This is a fierce argument if it makes a controversy. However, there is evidence that the use of mobile phones is associated with brain tumors, so this research may lead to bilateral discussions. Some results can be relieved. The brain will be activated within 50 minutes on a mobile phone will be less than when opening your eyes or listening to music. Others regard brain activation as early stage of cancer

I mean that this research implies that it is worthwhile to study carefully how cellular phones, cell phones, or the energy emitted by other energy-emitting devices on our head affect the brain I think with Dr. Volkow and other people. I also avoid 50 minutes of conversation (research period) on mobile phones and save them when I use headgear or old cordless earth wire.

According to an article written by former editor-in-chief Patrick J. Skerrett of Harvard University, the use of mobile phones to stimulate brain activity is neither good nor bad. However, the main concern is that excessive use of mobile phones may lead to brain tumors. It is known that a mobile phone antenna radiates radio frequency energy which is a form of nonionizing radiation. Because the nearest organizations can absorb it, health care professionals at the National Cancer Institute worry about how mobile phone use will affect user health.

How can a cell phone be secure if the mobile phone changes brain activity at a low level? If there are many studies showing that heavy mobile phone users have brain tumors, how can they be safe? Did the study show that sperm damage and brain damage at microwave radiation level are several thousand times lower than government regulation?

Studies published at the Journal of the American Medical Association showed that speaking on a mobile phone for 50 minutes, the brain's activity (Stemen) increased exponentially. Long-term effects are unknown, but response time and intelligence are higher than usual. Dr. Nora Volkow, a neuroscientist at the National Institutes of Health, the main author of this study, says: "Exposure to cell phones is easier to activate the brain than ever before It is shown that it is.

In our study, activity was found in a small factory near the bottom of the brain called the ventral side cover. We found activity in cells called A10 cells. It is actually a dopamine, a natural stimulant that sprays it into many areas of the brain. In fact, this part, the VTA is part of the brain's reward system. It's lower than your cognitive thinking process. It is part of what we call the nucleus of brain reptiles and is related to desire, motivation, concentration and desire. Indeed, when you feel a cocaine surge, we find that the same brain area of ​​activity has become active as well.
