Cell Phone Effect On Brain Metabolism

Use of a cell phone for as little as 50 minutes at a time appears to affect brain glucose metabolism in the region closest to the phones antenna a new study shows. Firstly with the cell phone on the right ear turned on for 50 minutes with the sound muted on state.

5 Scientists have reported adverse health effects of using mobile phones including changes.

Cell phone effect on brain metabolism. 22 2011 -- Cell phone use appears to have an effect on brain activity boosting the metabolism of brain glucose in. Individuals who are concerned about radiofrequency exposure can limit their exposure including using an ear piece and limiting cell phone use particularly among children. Cell phone use appears to have an effect on brain activity boosting the metabolism of brain glucose in specific areas according to a new study.

Investigators used positron emission tomography PET during cell phone use in the on and then off positions and found that although whole-brain metabolism was not affected metabolism was increased in the. Metabolism in the brain region closest to the antenna orbitofrontal cortex and temporal pole was significantly higher approximately 7 percent for cell phone on than for cell phone off. They have been studying whether imaging technologies including PET and magnetic resonance imaging MRI that are used to study the brain can directly affect brain function.

The team published Effects of Cell Phone Radiofrequency Signal Exposure on Brain Glucose Metabolism in the prestigious Journal of the American Medical Association. Cell phones were positioned on both the left and right ear while an image of the brain was captured using a PET brain scan together with an injection of 18F fluorodeoxyglucose to measure glucose metabolism in the brain. And secondly with both mobile devices.

Extended use of a cellular telephone causes increased activity in parts of the brain next to the phones antenna according to a new study in the Journal of the American Medical Association. There are no other clearly established effects on. A study by the National Institutes of Health in the US suggests that mobile phones could have an effect on the brain.

Although speculative one theory about how an artificial increase in brain glucose metabolism could be harmful is that it could potentially lead to the creation of molecules called free radicals which in excess can. They reported higher sugar use in the brain a sign of increased activity. From the WebMD Archives Feb.

Radiofrequency exposure from cell phone use does cause heating to the area of the body where a cell phone or other device is held eg the ear and head. This was performed twice. However it is not sufficient to measurably increase body temperature.

I wish my study could enlighten brain cancer risks added Volkow. She continues by pointing out that they have a stronger effect on children since their. Cell phone use appears to have an effect on brain activity boosting the metabolism of brain glucose in specific areas according to a new study.

The PET scan showed about a 7 percent increase in glucose metabolism in brain regions nearest to the cell phone antenna. The weak and erratic microwave radiation from cell phones and tablets cannot directly break the bonds that hold molecules together but it does disrupt DNA weaken the brains protective barrier and release highly reactive and damaging free radicals. February 23 2011 Use of a cell phone for as little as 50 minutes at a time appears to affect brain glucose metabolism in the region closest to the phones antenna a new study shows.

However whether acute cell phone exposure affects the human brain is unclear. For the past 15 years weve. Volkow is well known for her work in the area of addictions not generally adverse effects of cell phone use but this new study nevertheless stemmed from that research she said.
