    This paper presents an interesting approach to the problem of how ELF EM radiation impacts the human EEG. It would be interesting to see the "brain rate" topography immediately after the use of MP and compare it to the presented illustration. Construction of interpolated "equi-brain rate" lines could be one of the possible enhancements of the methodology. I would like to encouage the authors to continue this research.

    It is one of few papers considering extremely important problem of non-thermal effects of electromagnetic fields.

    I would suggest to compare the results with analysis of the same data using other methods of EEG-signal analysis.

    The references that are available on-line (open access) should be given with the appropriate web links.

    Some 'slips' in English e.g. 'bends' instead of 'bands', 'field in the brain (...) is spectral' ...

  • Other Comments:

    Authors are using brain rate to explain the possible benefical or detrimental roles of mobile phones though a possible indicator this seriously discounts the other effects of  cell phones that might be affecting other brain functions.

     The other studies pointed out by the authors were extensive yet failed to incoporate all the aspects of this complex problem. One  of the major drawback is use of cell phones and its role in brain  developmental abnormalities includinge brain tumor. This  is a complex issue that need to be addressed using multi prong approach.

The authors are thankful for your review and comments. In the revised manuscript , published on 30 January 2011, (1) the sections of results and discussion are expanded and (2) the information from illustrations is transferred to paper text, so that their number is very much reduced. Concerning your main objection which is related to not including the other effects of cell phones (noting that “one of the major drawback is use of cell phones and its role in brain development abnormalities including brain tumor”) the authors underline that these effects are out of the scope of the paper. This is additionally emphasized by a new sentence at the beginning of the chapter “Empirical evidence”.

  • Other Comments:

    The research idea of the paper is very timely and original. The main task of the paper is to review the published results on these topics and to present a discussion of the effects of mobile phone effects on human brain and mental activity. The paper concludes that EEG spectrum weighted frequency (brain rate), characterizing the level of mental arousal, can serve as a useful preliminary indicator of possible mobile phones influences.

    However, I would like to recommend to expand the section of results and discussion. More detail description of the EEG spectrum weighted frequency methodology would be an advantage. The number of pictures could be shortened easily by transferring the information from pictures to the paper text.

    I recommend this paper for final publication.

The authors are thankful for your valuable comments and suggestions. In the revised manuscript, published on 30 January 2011, all of them are taken into account, namely: (1) the sections of results and discussion are expanded, (2) the EEG spectrum weighted frequency methodology is described with more details and (3) the information from illustrations is transferred to paper text, so that their number is very much reduced (from 10 to 2).

    I could recommend pay more attention in the article for the discussion. The quality of the presented illustrations could be better. The illustrations are not acceptable.
