This is your brain on electricity

"Yes, Midge, I'm dying."

Whether cell phones hurt our brains -- and I'm not talking about the effects of chatting with your idiotic friends or having your boss find you on Saturday -- has been debated for years. A new study adds to the clamor:

Researchers from the National Institutes of Health have found that less than an hour of cellphone use can speed up brain activity in the area closest to the phone antenna, raising new questions about the health effects of low levels of radiation emitted from cellphones. 

The researchers urged caution in interpreting the findings, because it is not known whether the changes, which were seen in brain scans, have any meaningful effect on a person’s overall health.

As with the health effects of coffee, I urge you to remain calm: pour a cup and call a friend to talk this over.

The leader of the research, Dr. Nora D. Volkow, director of the National Institute on Drug Abuse, said:

“Unfortunately this particular study does not enlighten us in terms of whether this is detrimental or if it could even be beneficial. It just tells us that even though these are weak signals, the human brain is activated by them."

Dr. Volkow said future research may even show that the electromagnetic waves emitted from cellphones could be used to stimulate the brain for therapeutic reasons.

She said the research should not set off alarms about cellphone use because simple precautions like using a headset or earpiece can alleviate any concern. 

“It does not in any way preclude or decrease my cellphone utilization,” she said.

Never trust headlines: you have to read to the end of the New York Times article to get that.

"Hey, I have an idea!"

Meantime, we get this:

New scientific research suggests that by stimulating parts of their brains electrically, people can be induced to think more creatively than they normally do.  

The researchers took 60 normal, healthy, right-handed volunteers and asked them to try to solve a task that required clever insight. All of them were told they'd be receiving some kind of brain stimulation. But just 20% of the control group (who received no stimulation) could solve the task. That's compared with 60% of the volunteers who received electrical jolts to their brain--cathode stimulation of the left ATL (anterior temporal lobe) to suppress activity and anodal stimulation of the right ATL to increase activity.

Shocking.
