To determine whether extensive use of mobile phones affects brain metabolites detectable by proton magnetic resonance spectroscopy.
Proton magnetic resonance spectroscopy allows one to non-invasively examine the brain by measuring the levels of several metabolites reflecting for example neuronal condition and membrane metabolism.
21 mobile phone users and 15 control subjects were studied.
|Setup||the mobile phone was held to the right ear|
No parameters are specified for this exposure.
No statistically significant changes in the N-acetylaspartate/creatinine, choline/creatinine and myo-inositol/creatinine ratios were measured between mobile phone users and control subjects and between the exposed and contralateral temporal areas, i.e. extensive exposure to mobile phone does not cause proton magnetic resonance spectroscopy-detectable brain metabolic changes.
