Pulse flows of populations of cortical neurons under microwave irradiation: Burst activity

Impulse Trains Generated by Populations of Cortical Neurons of Rabbits Exposed to Low-Intensity Extrahigh-Frequency Electromagnetic Radiation: Bursting Activity

“…Third, clearly pronounced shifts were observed after cessation of the EHF influence but not only within the exposure to radiation. These differences perhaps resulted from a supposedly nonlinear dependence of the effects of EHF irradiation on the intensity of this influence [11].…”

“…It was demonstrated [15] that the variability of neuronal activity can be neutralized in the functioning of the brain as a whole and also of separate cerebral structures at the expense of averaging neuronal ensembles. This approach allowed us to find that EHF irradiation induced mild changes in the frequency but more significant structural rearrangements of background impulse successions produced by populations of cortical neurons [8,[10][11][12][13]. In these studies, interest was concentrated on bursting activity directly related to the functioning of certain neuronal circuits.…”

“…Information on the effects of decimeter-range EHF radiation on the functioning of central neurons of mammals remains rather limited [6][7][8][9][10][11][12][13]; in some aspects, our studies are pioneering. The history of the problem was described in our earlier publication [14].…”

“…In our earlier experiments where we analyzed electrical potentials in different cerebral structures and used a number of surgical operations, we demonstrated that direct action of electromagnetic fields (EMFs) of different frequencies, as well as that of magnetic fields (MFs), on cerebral tissues plays a leading role in the genesis of electrical reactions of cerebral structures [1][2][3]. It is obvious that the effects of electromagnetic extrahighfrequency (EHF) radiation should be studied, first of all, at the level of the cerebral cortex, since such radiation cannot significantly influence deeper cerebral structures [4,5].Information on the effects of decimeter-range EHF radiation on the functioning of central neurons of mammals remains rather limited [6][7][8][9][10][11][12][13]; in some aspects, our studies are pioneering.

“…As such electrodes, we used glass micropipettes (tip diameter 20 µm) filled with 1% agar based on physiological saline. The technique was described in detail earlier [8,[10][11][12][13]. Experiments were carried out in accordance with the guiding ethical principles of care for and use of laboratory animals proposed by a directive of the Council of European Communities (86/609 EEC).…”
