Alleghiamo l’Abstract di un art. scientifico pubblicato su “Prague Medical Reports”, 2005; 106 (1): 91 – 100, in cui viene riportato che esponendo dei topi al campo elettromagnetico a frequenze della telefonia mobile si influenza l’attività cerebrale nei topi, e precisamente si dimostra un effetto sull’attività della corteccia cerebrale e dell’ippocampo.
Gli autori concludono affermando che i risultati del loro studio costituiscono una conferma che il campo elettromagnetico generato dai cellulari può influenzare l’attività del sistema nervoso centrale, e costituiscono altresì una conferma di alcune recenti ricerche sui possibili rischi per la salute umana a causa dell’uso dei cellulari.

A direct registration of brain cortical and hippocampal activity during a high-frequency electromagnetic field (HF EMF) exposure was performed. All experimental procedures were done under urethane anaesthesia (20%, 2 g/kg i.p.) in Lurcher mutant mice, wild type (healthy littermates) were used as controls. Experimental animals were exposed to the HF EMF with frequency corresponding to cellular phones. Our method is based on the use of gel electrodes (silicon tubes or glass microcapillaries filled with agar) where the connection with classical electrodes is located out of HF EMF space. ECoG evaluation showed a distinct shift to lower frequency components but clear effect has been observed only in wild type (healthy) mice whereas in Lurcher mutant mice only gentle differences between frequency spectra were found. Measurement of hippocampal rhythmicity showed gentle changes with increase of higher frequencies (i.e. opposite effect than in cortex) and changes in theta oscillations registered from a dentate gyrus and CA1 area in both types of animals (healthy and mutant). These findings support the idea about possible influencing the central nervous system by HF EMF exposure and support also some recent results about possible health risks resulting from cellular phones use.
