dc.description.abstractMobile phones create a radio frequency electromagnetic field EMF around them when in use the effects of which on brain physiology in humans are not well known We studied the effects of a commercial mobile phone on regional cerebral blood flow rCBF in healthy humans using positron emission tomography PET imaging Positron emission tomography data was acquired using a double blind counterbalanced study design with 12 male subjects performing a computer controlled verbal working memory task letter 1 back Explorative and objective voxel based statistical analysis revealed that a mobile phone in operation induces a local decrease in rCBF beneath the antenna in the inferior temporal cortex and an increase more distantly in the prefrontal cortex Our results provide the first evidence suggesting that the EMF emitted by a commercial mobile phone affects rCBF in humans These results are consistent with the postulation that EMF induces changes in neuronal activity
