“…The question of whether the deliberate and passive exposure to radio frequency (RF) EMF from mobile phones might affect cognitive functions is of great importance. Reports of impairment [Maier et al, 2004;Keetley et al, 2006] or improvement [Preece et al, 1999;Koivisto et al, 2000] of cognitive performances in humans are countered by findings that no changes occur [Haarala et al, 2003[Haarala et al, , 2007Russo et al, 2006]. It is vital to realise that in these mentioned studies, the mobile phone exposure is within existing exposure guidelines from the International Commission on Non-Ionising Radiation Protection [ICNIRP, 1998] with a specific energy absorption rate (SAR) <2 W/kg for exposure to the head of humans.…”

Considering the frequent use of mobile phones, we have directed attention to possible implications on cognitive functions. In this study we investigated in a rat model the long-term effects of protracted exposure to Global System for Mobile Communication-900 MHz (GSM-900) radiation. Out of a total of 56 rats, 32 were exposed for 2 h each week for 55 weeks to radio-frequency electromagnetic radiation at different SAR levels (0.6 and 60 mW/kg at the initiation of the experimental period) emitted by a (GSM-900) test phone. Sixteen animals were sham exposed and eight animals were cage controls, which never left the animal house. After this protracted exposure, GSM-900 exposed rats were compared to sham exposed controls. Effects on exploratory behaviour were evaluated in the open-field test, in which no difference was seen. Effects on cognitive functions were evaluated in the episodic-like memory test. In our study, GSM exposed rats had impaired memory for objects and their temporal order of presentation, compared to sham exposed controls (P = 0.02). Detecting the place in which an object was presented was not affected by GSM exposure. Our results suggest significantly reduced memory functions in rats after GSM microwave exposure (P = 0.02).

“…Some studies of human cognitive functioning have shown that exposure to electromagnetic fields of the type emitted by mobile phones can affect cerebral functions (e.g., Hamblin et al, 2004) as well as the behavioral performance of exposed volunteers (e.g., Keetley et al, 2006;Koivisto et al, 2000). Other studies, however, have found no significant effects either on human behaviour (Russo et al, 2006;Haarala et al, 2004), or on brain processes (e.g., Krause et al, 2003).…”

The effect of acute exposure to radio frequency electromagnetic fields (RF EMF) generated by mobile phones on an auditory threshold task was investigated. 168 participants performed the task while exposed to RF EMF in one testing session (either global system for mobile communication (GSM) or unmodulated signals) while in a separate session participants were exposed to sham signals. Lateralization effects were tested by exposing participants either on the left side or on the right side of the head. No significant effect of exposure to RF EMF was detected, suggesting that acute exposure to RF EMFs does not affect performance in the order threshold task.

The effects of electromagnetic radiation of mobile phones on the central nervous system have been studied by Hossmann and Hermann [6] and the thermal effects of radiation from cellular telephones have been studied by Wainwright [7].…”

We consider a problem of skin tissue of the human head subjected to thermal diffusion with relaxation time. The bounding surface of the tissue of the human head is subjected to a thermal shock. The chemical potential is also assumed to be a known function of time on the bounding plane. Laplace transform techniques are used and the results are obtained numerically using a numerical method for the inversion of the Laplace transform based on Tzou method. The temperature distribution and the concentration distribution are obtained and represented in figures. According to the results, the values of the time and the distance have significant effects on the temperature increment and the concentration. The values of the temperature increment and the concentration increase when the time increases and decrease when the distance increases.
