Nonlinear EEG activation evoked by low-strength low-frequency magnetic fields

Numerical analysis of recurrence plots to detect effect of environmental-strength magnetic fields on human brain electrical activity

“…The evoked potentials were not detected when the EEGs were analyzed by time averaging, indicating that they were not timelocked but rather nonlinear in origin, as observed previously [6,13,14]. The finding that the changes in recurrence parameters could be either an increase or a decrease (Fig.…”

“…Filtering within the alpha band was sometimes necessary for detection of the evoked potentials (Table 1), as observed previously [6,13,14]. The amount of alpha power, the levels of which are generally associated with alertness [16], varied from subject to subject (Fig.…”

“…Filtering the EEG in the alpha band facilitates detection of MEPs; sometimes filtering 9-12 Hz but not 8-10 Hz was effective, and sometimes conversely [6,13,14]. Sometimes both %R and %D revealed a field-induced change in the EEG, but sometimes only one or the other did so [14].…”

Non-linear recurrent analysis of the behavior of a complex technological object

“…Establishing the manifestations of intermittency during the control of technological processes of sugar manufacturing will make it possible to apply adaptive efficient methods of decision making in accordance with the character of the behavior of the object that will lead to saving material and energy resources. The paper [5] proposed the method of analysis of nonlinear dynamic systems that expands the possibilities of nonlinear time series analysis, based on the fundamental property of dissipative dynamical systems recurrence (repeatability of states). It is obvious that this method of analysis, based on the representations of properties of the processes in the form of geometric structures, may become a tool for determining dependencies in the observed processes.…”

Identification of a Novel Rat NR2B Subunit Gene Promoter Region Variant and Its Association with Microwave-Induced Neuron Impairment

“…In populations, the prevalence of self-reported electromagnetic hypersensitivity has usually been attributed to somatization disorders [11,12]. A possible nonpsychological basis for electromagnetic hypersensitivity was evidenced by the occurrence of field-onset and field-offset brain potentials [13], and the induction of steadystate changes in brain electrical activity that persisted in the presence of the field [14], but the mechanism is still not clear.N-methyl-d-aspartate receptors (NMDARs) represent a unique family of central synaptic receptors, with members that differ widely in their biophysical and pharmacological Li-Feng Wang and Da-Wei Tian are co-first authors. …”
