“…The retrosigmoid craniotomy directly exposes the eighth nerve to mobile phone EMF without any biological structure in between. This condition is clearly far from reproducing the real-life EMF absorption of neural structures, because it offers a reliable measurement of the direct effect of a known EMF on a sensitive nerve without the interposition of other structures (skin, skull, fat, muscle, blood, grey and white matter) that have different SAR 17 42. All these structures play an important role in determining the SAR of inner-ear structures in responses to EMF exposure 29…”

“…One early study by Kellényi et al [1999] reported a significant effect on ABR but they failed to replicate this finding [Stefanics et al, 2007]. The effects of mobile phone radiation with a weak transmission power could be transient, but only a few studies applied concurrent exposure during ABR measurements [Bąk et al, 2003;Sievert et al, 2005;Kwon et al, 2010b].…”

“…The spatial average SAR in the user's head would be the maximum output divided by the mass of the head, but local peak values can be much higher depending on the distance to the phone and tissue type [Kwon et al, 2010b].…”

For the last two decades, a large number of studies have investigated the effects of mobile phone radiation on the human brain and cognition using behavioral or neurophysiological measurements. This review evaluated previous findings with respect to study design and data analysis. Provocation studies found no evidence of subjective symptoms attributed to mobile phone radiation, suggesting psychological reasons for inducing such symptoms in hypersensitive people. Behavioral studies previously reported improved cognitive performance under exposure, but it was likely to have occurred by chance due to multiple comparisons. Recent behavioral studies and replication studies with more conservative statistics found no significant effects compared with original studies. Neurophysiological studies found no significant effects on cochlear and brainstem auditory processing, but only inconsistent results on spontaneous and evoked brain electrical activity. The inconsistent findings suggest possible false positives due to multiple comparisons and thus replication is needed. Other approaches such as brain hemodynamic response measurements are promising but the findings are few and not yet conclusive. Rigorous study design and data analysis considering multiple comparisons and effect size are required to reduce controversy in this important field of research.

“…A recent study concluded that short-term exposure to mobile phone EMFs did not affect the transmission of sensory stimuli from the cochlea up to the midbrain along the auditory nerve and the brainstem auditory pathways [21]. A study in Poland evaluated the ABRs in 45 young healthy volunteers before, during and after exposure to EMFs generated by antenna of a mobile phone.…”

There has been a manifold increase in the number of mobile phone users throughout the world with the current number of users exceeding 2 billion. However this advancement in technology like many others is accompanied by a progressive increase in the frequency and intensity of electromagnetic waves without consideration of the health consequences. The aim of our study was to advance our understanding of the potential adverse effects of GSM mobile phones on auditory brainstem responses (ABRs). 60 subjects were selected for the study and divided into three groups of 20 each based on their usage of mobile phones. Their ABRs were recorded and analysed for latency of waves I-V as well as interpeak latencies I-III, I-V and III-V (in ms). Results revealed no significant difference in the ABR parameters between group A (control group) and group B (subjects using mobile phones for maximum 30 min/day for 5 years). However the latency of waves was significantly prolonged in group C (subjects using mobile phones for 10 years for a maximum of 30 min/day) as compared to the control group. Based on our findings we concluded that long term exposure to mobile phones may affect conduction in the peripheral portion of the auditory pathway. However more research needs to be done to study the long term effects of mobile phones particularly of newer technologies like smart phones and 3G.
