Brain glucose metabolism increased by mobile phone use

RADIOFREQUENCY radiation exposure from a 50-minute mobile phone call increases brain glucose metabolism in regions closest to the phone’s antenna, a study shows. 

Among 47 healthy study participants, US researchers found brain glucose metabolism was significantly higher in the orbitofrontal cortex and temporal pole when mobile phones were turned on rather than turned off.

The results suggested brain absorption of radiation may “enhance excitability” of brain tissue, but the study could not determine if mobile phone use triggered carcinogenic effects, they said.
