INTRODUCTION
Studies of impact, produced by electromagnetic field (EMF) and radiation (EMR), emitted by mobile phones (MP), on biological organisms have actively been conducted over the last two decades. However, the literature showed no clear correlation of negative impact with radiation, emitted by MP, at least until 2000. In order to clarify this issue, the WHO established the INTERPHONE project. Studies were conducted in 13 countries. 12,800 people participated in the studies. 20mln pounds were spent. The findings of the studies made it possible for the WHO specialists to confirm connection between MP use and brain tumors, manifestation of Alzheimer and Parkinson diseases, epileptic seizures provocation. Preliminary findings were published in The Daily Telegraph in 2009. The mobile phone is a source of complex-modulated electromagnetic radiation of SHF (centimeter) band. Depth of MP SHF EMR with frequency up to 1000MHz penetration into the brain makes up to 1.93cm (6). Thus, it is possible that MP EMR directly impacts not only the cells of closely adjacent areas, but also on the whole brain, including liquid media thereof. This changes functional state of the central nervous system (CNS), which is reflected in the bioelectrical activity pattern (BEA) of the brain (1,3,4,7,8,10,13,14,16,17). However, not all researches support the idea of weak EMR, emitted by mobile phones, negatively impacting the brain (14). The opinion is favored by the researchers, focusing their attention on exposure to energy of radiation, emitted by mobile phones, which is measured by SAR (Specific Absorption Rate). Modern phones, generally, have SAR below the acceptable standards. Moreover, manufacturers state that receiver sensitivity is better in expensive phones and smartphones, which enables to increase communication distance and also to use less powerful transmission unit of the basic station. From their vantage point, this suggests that modern mobile communication is harmless.
The purpose of this paper is to assess aspects of cerebral BEA upon exposure to EMR of the modern phone in the conversation mode and possible compensation of emerging negative physiological effects, using the AIRES SGIELD Pro corrective device.

STUDY POPULATION, SCOPE AND METHODS
We used Prestigio modern smartphone in this study. 13 apparently healthy 21 - year old male volunteers participated in the study. The tests conformed to ethical principles of the Declaration of Helsinki of the World Health Organization 2000 and were performed by double-blind method with the informed consent from the volunteers. The statistical group included 6 persons. The entry condition was stability of the functional state of the body (according to EEG and ECG values) during one -two weeks of the study (April 5, 2019 – April 18, 2019).
EEG and ECG values were recorded, using Etsefalan 131 03 software solution with integrated EEG and ECG recording and analysis programs. Cerebral BEA (EEG) was recorded, using 16 monopolar leads according to the international 10-20 system of electrode placement in the 0-70Hz bandwidth with 250Hz sampling frequency. The electrodes were placed symmetrically in the prefrontal (Fp1, Fp2), postfrontal (F3, F4), frontotemporal (F7, F8), central (C3, C4), midtemporal (T3, T4), posttemporal (T5, T6), bregmatic (P3, P4) and occipital (O1, O2) regions, while integrated reference electrodes were placed on ear lobes. The even electrodes were placed on the right side.
The scenarios for the study:
1. EEG and ECG recording and analysis according to the requirements and criteria
of functional diagnostics (visual analysis) and selection of subjects in to the statistical group. 13 subjects. 2. Recording I – background EEG (2min); eyes opening and closing test; II –
background with eyes closed (audio frequency oscillator – 2min); III – EEG recording with the mobile phone On (MP ON – muted conversation mode), in the fronto-temporal region on the right side (5min); IV – recording after MP is off (MT after test -2min). 6 selected subjects. 3. Recording I - background EEG (2min); eyes opening and closing test; recording
II - background with eyes closed (audio frequency oscillator – 2min); III - EEG recording with the mobile phone On + AIRES SHIELD (MP+ - muted conversation mode), in the fronto-temporal region on the right side (5min); IV - EEG recording after MP+ is off and after test (2min). 6 selected subjects.
The subjects did not know if scenario II or III was used during the study.

Five random 5-second segments were studied in each scenario sample. Power spectrum, amplitude, EEG bands index, asymmetry of the dominant rhythm, correlation analysis were evaluated. As the sample was small (6 subjects), integrity of the findings was assessed, using non-parametric sign test.
FINDINGS AND DISCUSSION OF IN-HOUSE STUDIES
Five subjects of the statistical group had stable EEG patterns of the same type. Alpha activity prevailed in the EEG of the above-mentioned subjects while waves were distributed by the amplitude with decrement from the back of the head to the forehead. Frequency: 9.8±0.2 oscillations per second. Amplitude: 80.0±7.0μV. Index: 85±17%. No significant variations of the average alpha activity frequency and the average amplitude were seen in the subjects during the background recording from one study to another.
The sixth subject was specifically included into the statistical group for comparison . This subject had an unstable EEG pattern not only during the three studies, but also during the first background study, scattering of low-amplitude beta rhythm, diffused vascular pulsations were observed in the subject as well. Nevertheless, values of basic rhythms, their distribution and correlation were within the limits.
Hyperventilation (HV) is a functional test, adopted in the clinical electroencephalography. This test causes development of hypoxia and hypercapnia – forced physiologically substantiated change of the functional state of the CNS. Generally, aftereffects of the HV include development of slow wave activity, while, in pathological cases it provokes development paroxysmal activity. When the test is over, BEA shift towards slow wave activity prevalence continues no more than 5-15s.
In all subjects of the statistical group, including the sixth subject, HV aftereffects stayed within the above-mentioned limits of BEA changes, no paroxysmal activity was detected. Development of spectral power density in the slow wave area of EEG band and in the alpha band, enhancement of coherence in all bands, increase of the correlation coefficient in the temporal leads (to a lesser extent in the sixth subject, B-v) were observed. The ATTACHMENT hereto includes examples of encephalic asymmetry visualization based on reciprocal functions: cross-spectrum (CS), coherency (COH), cross-correlation (CC) after the HV in the patient with a stable BEA pattern (Fig. 2 A1 – A3¹) and in the sixth subject (Fig. 3 A1 – A3¹)
The main differences between the subjects of the statistical group and the sixth subject were evident upon exposure to the MP and MP+, i.e. in the presence of the AIRES SHIELD. As for the statistical group, 7-13 seconds after the MP was turned on,
7
EEG pattern changed gradually. The pattern with a prevailing alpha activity (Fig. 1A) was replaced by the pattern with a prevailing slow wave activity (Fig. 1B), dominance of delta waves with an emphasis on the MP side (r≤0.01) was observed, thus reflecting change of the functional state of the brain. The BEA pattern was similar upon exposure to the MP and during the MP aftereffect as well as after the HV. However, while after the HV EEG promptly went back to the background values, even 2 minutes after the MP was turned off, EEG slow wave activity still prevailed. Positron -emission tomography (J.am.Med. Association, 2010) showed that brain cells absorb glucose with 2.4 speed in the areas where the MP is applied (orbitofrontal cortex and the front part of the temporal cortex), indicating hyperactivation of these areas upon exposure to EMR, emitted by the MP. It is to be noted that prolonged hyperactivation may cause damage to these parts of the brain, which are responsible for learning, memory, planning and development of motor programs. General BEA pattern upon exposure to EMR, emitted by the MP, and during the MP aftereffect is similar to the BEA pattern in the hypnotic sleep or meditation, i.e. altered state of consciousness. It should be noted that during aftereffect of EMR, emitted by the MP, prevalence of slow wave activity continued for more than 2-3min. Extension of such a condition is most hazardous for children’s mind during the process of formation thereof (11, 12).
As for combination with the AIRES SHIELD, when the MP was turned off, cerebral bioelectrical activity immediately went back to the initial state, similar to aftereffect of the HV (Fig. 1B). Even though there was a visual similarity of the initial EEG pattern (the background prior to turning on of the MP) and the pattern after exposure to the MP in combination with the AIRES SHIELD, statistical analysis showed valid (r≤0.05) differences. The differences included increased frequency of alpha rhythm from 9.8±0.2 to11.6±0.3 oscillations per second. Neurophysiologists of the late 20c – 21c (2, 5, 9) believe that the higher alpha rhythm frequency is, the higher the speed of information perception and processing thereof is. However, this conclusion has to be experimentally tested within the framework of future studies on efficiency of the AIRES SHIELD, used as the device, neutralizing negative impact of exposure to EMR, emitted by the MP. Findings of the comparative BEA encephalic asymmetry (ECA) changes assessment (see ECA visualization patterns and data, provided by G.N. Lukyanov) upon exposure to EMR, emitted by the MP with and without the AIRES SHIELD showed that when the MP was used in combination with the AIRES SHIELD, coherence structure changed, i.e. electrons arrangements, indicating harmonized behavior of oscillation processes and interactions of brain structures and parts. Harmonization is necessary for ‘cost-free’ optimization of processes in the CNS. In complex systems harmonization is performed not only and not so much through oscillation phases, but also via correlations. Our study also showed change of
8
correlation links structure between cortical parts of the brain. Comparing different stages of the study, we see that the structure has become more sophisticated: against the background of exposure and after exposure, in particular, in the frontal region, where behavioral programs are developed, and in the right temporal region, where the operating MP is located. As a result, the brain gradually becomes more resilient to negative impact of EMR, emitted by the MP.
A different pattern of exposure to the MP was observed in the sixth subject . When the MP was turned on, bursts of alpha activity with 11-13 oscillations per second frequency were recorded against the background of slow wave rhythms. Amplitude of such alpha activity was the greatest before the MP was turned off (4th, 5th minute). It was similar to sleep spindles at the end of exposure to the MP and during aftereffect of the MP in combination with the AIRES SHIELD. In this case, subject to unsteadiness of the initial EEG pattern, tension of cortical vessels was evident, which was manifested by vascular pulsations, sharpness of alpha waves peaks due to high -frequency activity. This BEA pattern is an indicator of shift in the activity – inactivity balance towards slight predominance of activation processes as a result of the brain cortex excitation . Upon exposure to the MP and the MP+ (in combination with the AIRES SHIELD), the brain, first of all, responded to low-frequency modulating signal (2 oscillations per second). Afterwards the brain searched for the optimum way to compensate changes, caused by exposure to the MP: corrective regulatory structures of the diencephalic system were engaged. In the latter case bursts of alpha waves against the background of slow wave activity mostly indicated that the process of the BEA changes correction involved not only regulatory subcortical structures, but also the cardiovascular system, which was manifested by synchronization with ECG (electrode 18, see Fig. 3). As is shown in the diagrams below, benchmarking clearly demonstrated that exposure to the MP disrupts fractional structure of EEG, which is characteristic to background studies (see the first diagram). Such a structure reflects interaction of structures of the central nervous system (see the diagram in the middle). Upon exposure to the MP in the presence of the AIRES SHIELD, destructive influence of the working mobile phone is significantly weakened (see the third diagram). The calculation was specifically performed by electrodes on the left side, including the reference electrode A1 to exclude possible physical artefact from the MP, placed at the right ear.
From the standpoint of modern science, a biological organism is a multiple - component, dissipative, fractally organized, non-linear, self-regulating system. The prime objective of a biological system being a single structure is survival in the changing environment. The system has a multi-layer subordinate structure with dynamically arranged hierarchy of self-regulating processes. Resonance response to biologically significant multi-frequency impacts of informational nature is a basic
9
property of biological systems. However, the system is non -linear, therefore, response depends on the initial state and requires non-linear approach to assessment of the state change. Otherwise, analysis of the calculations may be incorrect. Thus, a significant discrepancy may be detected upon visual comparison of EEG pattern and visualized encephalic asymmetry. It is due to the fact that when EEG spectrum is broken down into bands, using the Fourier filters, coherence seemingly enhances over all bands, including alpha and beta ones, nevertheless, the BEA pattern includes virtually no alpha or beta waves. The main conclusions are confirmed by more precise proc essing of EEG signals, the findings of which are presented by prof. G.N. Lukyanov in the diagrams below.

Fig.4. Example of reciprocal spectral power density for signals from electrodes O1 (occipital left) and P1 (sincipital left). The upper figure – before exposure, the figure in the middle – exposure to the MP, bottom figure – exposure to the MP in combination with the resonator (AIRES SHIELD). The diagram in the middle clearly shows an additional peak, emerging at 6Hz frequency upon exposure to the MP. During exposure to the MP in combination with the resonator (bottom diagram), the peak disappears, which may be considered as return to normal state.
