We investigated the influence of the vortical impulsive mag­netic fields (MF), created by the rotation of their source in right and left direction, on the total background electric activ­ity anterior hypothalamic (AHA) and dorsal hypothalamic areas (DHA) in rat brain. It is shown, that under the action of such MF in electrohypothalogramms (EHtG) of both investigated areas there was a substantial increase of spectral power of middle frequencies waves (teta–, alfa–diapasons) as compared to control absolute power of waves in all frequency ranges of EHtG, that testified to growth in such terms of activity of the synchronizing rhythm-formative systems of brain. The indicated changes were more pronounced in AHA, which contains centers of adjusting of trophotropic reactions. The investigated descriptions of EHtG at the action of MF of right rotation changed more substantially, than under influence of left directed MF, that indicates on different biological effi­ciency of the indicated fields.

Keywords: the vortical impulsive magnetic field, hypotha-lamic electric activity, electrohypothalogramm.
