Summary/Abstract: The dynamics of spectral composition of electric activity in the trophotropic and ergotropic areas of the rat hypothalamus during long time stress (21 week) and action of the left directed vortical impulsive magnetic field (MF) were investigated. It was discovered that effects of vortical MF influence depend both on the initial state of studied cerebral structure and the period of influence. Under physiological condition the MP influence leads to synchronization in spectral composition of electrohypotalamogramme (EGtG) that was expressed by theta-rhythm increasing. The formation of diphasic EGtG as a successive replacement of the desynchronization by synchronization of electric activity due to high-frequency components was observed under the combined influence of stress and MF.
