Pulse flows of cork neuron populations under microwave irradiation of different intensity

Abstract

The one-minute effects of the microwave field (wavelength 37.5 cm, power density 0.2-0.3; 0.4; 0.5, and 40 mW/cm²) on the impulse flows of cortical neurons of awake non-immobilized rabbits were investigated. Interpulse intervals were considered within a minute before exposure, during exposure and within one minute after. The changes that occurred on the side of the interspike intervals as a result of these impacts were analyzed. It was found that in the case of irradiation intensities of 0.2-0.3 and 0.4 mW/cm², the average values of interspike intervals predominantly decreased, and at irradiation intensities of 0.5 and 40 mW/cm² shifts in the values of interspike intervals of the opposite direction prevailed. The smallest changes in interspike intervals were observed at an intensity of 0.4 mW/cm². The work shows that microwave irradiation with a one-minute exposure causes rearrangements in the impulse flows of populations of cortical neurons. The rearrangements of neuronal activity that occur under the influence of one-minute microwave irradiation consist of visually predominantly separate shifts during and after exposure with additional fluctuations and indicators within these periods, which is similar to the encephalograms we studied earlier. The studies carried out are necessary for understanding the electromagnetic situation on the Earth and for the analysis of the corresponding space-related problems.
