Using application of natrium salt of benzilpenicillin of various concentration (10.000 and 50.000 IU/ml), foci of correspondingly weak and strong intensity were modeled in brain cortex of Vistar line rats. Action of extremely high frequency (EHF) electromagnetic radiation (EMR) of low intensity (7.1 mm, 0.1 mW/cm2) directly on the zone of generation of epileptic discharges was accompanied by depression of intensity of epileptic activity (EpA) of weak foci of epileptogenesis (exposition 5.0 and 15.0 minutes) and increased generation of EpA in strong foci (exposition 15.0 minutes). The influence on brain cortex before epileptogen application was accompanied by appearance of EpA weak foci intensity depression effect in various expositions of EMR and strong intensity foci depression under exposition of EHF of 15.0 minutes.
