BIOPOTENTIALS OF THE CEREBRAL BRAIN ON INFLUENCE OF CONSTANT MAGNETIC FIELD

Abstract

Results of many-sided investigations of rearrangements of biopotentials of the
cerebral brain occurring under constant magnetic field (CMF) were considered. In rabbits was es-
tablished, that 1-min action of CMF of intensity 460 e produces rearrangements EEG as rise of its
amplitude and increase of the number of spire bursts In was found a role of method of switching on
and off of electromagnet upon development of these rearrangements of EEG. Switching on of elec-
tromagnet through reostat raised probability and intensity of rearrangements of EEG, that shows
participation of induction in development of rearrangements of biopotentials direct under influence
of CMF. In connection with that, complex dynamics of development of electrical reaction on CMF,
including events during and after influence, occur. It is necessary to recognize, that rearrangements
of biopotentials under action of CMF touch not only the neocortex, but affect on condition of dif-
ferent formations of the brain. Type of these changes depends by starting special of pattern of po-
tentials. It can suppose, that investigated structure of changes of biopotebtials of the brain upon in-
fluence of CMF represents functional rearrangements in action of the brain, what can develop under
another circumstances. Really, similar changes were found in these animals under influence of
sound stimulation (tone 200 Hz, intensity 0.012 din/cm2).
