Investigation of brain potentials in sleeping humans exposed to the electromagnetic field of mobile phones.

چکیده
An investigation was made of 8-hour EEG tracings of sleeping humans exposed to the electromagnetic field of a GSM-standard mobile phone. To analyze the EEG-patterns, manual scoring, nonlinear dynamics, and spectral analysis were employed. It was found that, when human beings were exposed to the electromagnetic field of a cellular phone, their cerebral cortex biopotentials revealed an increase in the alpha-range power density as compared to the placebo experiment. It was also found that the dimension of EEG correlation dynamics and the relation of sleep stages changed under the influence of the electromagnetic field of a mobile phone.

متن کاملMobile phone exposure during pregnancy disrupts learning and memory in rat offsprings
Abstract Introduction: Mobile phones create high-frequency electromagnetic fields around them when in use. The close proximity of mobile phones to the user’s head leads to the absorption of part of the electromagnetic waves into the head and the brain. Methods: We have elucidated the alteration in cognitive function of the male and female offspring rats, which were exposed to chronic mobi...
