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' ...

The paper is recommended for acceptance. The topic is important for
the researchers working in this field. The coverage of the topic is
only introductory type. The paper as a technical note or suggestion is
OK.

This is the first paper which shows that the effect pf mobile phones should be presented in terms of the inverted U-law of brain performance.

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.

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 main goal of the article is to present the published results and a possible explanation of mobile phone effects on human brain and mental activity. The results analysed in the paper published in the high quality journals. The topic of the article is extremely important.
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.

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.
