Cellulari ed attività cerebrale

Inviamo l’Abstract di un art. scientifico pubblicato sul “Journal of Cerebral Blood Flow & Metabolism, n. 26, 2006.

Viene dimostrato, mediante l’uso della tomografia PET, che il cellulare influenza il flusso del sangue cerebrale umano.

I risultati sono consistenti, affermano gli autori, con il fatto che tali campi elettromagnetici determinano cambiamenti nell’attività neuronale.

Mobile 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.
