Researchers at the National Institute of Health published a study of correlation between cell phone use has increased brain activity in the region, primarily the antenna of the phone with a significant increase in the amount of cerebral glucose metabolism in the orbitofrontal cortex region front of the brain near the ear.
Scientists are unsure of the impact of these increases to their health.
The study, conducted in 2009, focused on 47 participants who have a positron emission topography scan as they spent 50 minutes with a phone attached to their ear.
Nora D. Volkow director of the study group, said the ambiguity of the research report, The New York Times.
“Unfortunately this particular study does not enlighten us in terms of whether this is detrimental or if it could even be beneficial,” Volkow said. “It just tells us that even though these are weak signals, the human brain is affected by them.”
Mark Lenzenweger, distinguished professor of psychology at Binghamton University, said he believes it’s too early to tell.
“It’s important not to jump to causal conclusions. It’s food for thought,” Lenzenweger said.
The inconclusive nature of the study has had a mixed reaction from BU students.
“Physically, I don’t think its harmful,” said Levi Cleare, an undeclared freshman. “You really don’t hear many stories about people having brain illnesses caused by talking on their cell phone.”
“We’re bombarded with all sorts of radiation every day, so while it may be interesting, I’m not going to panic,” said Sam Williams, a freshman majoring in chemistry.
In addition, because the study was based on conversations of 50 minutes, many are skeptical about the effectiveness of shorter talks on the brain.
Jason Marchione, a senior majoring in sociology, is undeterred by the study.
“I don’t believe that the amount of time someone spends on the phone makes a big difference,” he said.
Other students feel this study lends credibility to the idea that cell phones have a negative effect on one’s health.
“Personally, I try, if I don’t really have to, not to use my cell phone,” said Katherine Rimpel, a freshman majoring in biochemistry. “Even though people say it doesn’t cause cancer, there is some radiation being emitted from the phone.”
According to a Wall Street Journal, there may be evidence that cell phones help the fight against depression. The increases observed in this study are comparable to transcranial magnetic stimulation, a treatment used struggle against clinical depression.
Tousif Ahsan, a freshman political science, took a different approach.
“Maybe it is a good thing,” he said. “I’ll start doing my homework with cell phones taped to my head.”
While 7-8 percent difference in brain activity were found between the on and off the phone, the research is preliminary. Investigators have not done anything beyond the requirements from growth in glucose metabolism.
Although most studies debunk the theory that radiation from mobile phones causes brain cancer, some professionals in the field notes that the NIH study points to the effort to truly understand how cell phone use can affect the brain.
