GLIAL REARRANGEMENTS IN THE CEREBRAL CORTEX UNDER CONSTANT MAGNETIC FIELD

Abstract

Results of investigations of morphological rearrangements in the cerebral cortex
under constant magnetic field (CMF) were considered. Action of CMF of intensity 460 e during 3
min., 15 min. and 1 hr in the cerebral cortex of unanesthetized and unrestrained rabbits produced
change of the general number of glial elements, and too the general number of perineuronal satel-
lites. Basic effect mainly was contained in rise of these numbers under action of CMF. Maximum
changes were under action CMF during 15 min. Then the of level of the general number of glial
cells and too the general of perineuronal satellites reached 40 %/ More long action of CMF de-
creased expression of reaction. Simultaneously the numbers of perineuronal satellites beside sepa-
rate neurons were analysed. The numbers of revealed satellites were from 0 to 4. Increase of the
number of events with absence of perineuronal satellites in neurons was particularly during 15-min.
