Antiepileptic effects of short-wave radiation in hypogeomagnetic conditions

The work was dedicated to investigation of dynamics of epileptic activity in conditions of extremely high frequency electromagnetic waves (EHF) radiation (7,1 mm, 0,1 mW/cm 2 ) upon focal epileptic activity. Epileptic activity was penicillin-induced (10,000 IU/ml) in the frontal region of the brain cortex in myorelaxed and artificially ventilated rats under acute experimental condition. Thermal effects were absent as far as absorbed dosage of energy did not exceed 0,1 J/ animal. It was established that preliminarily performed hypogeomagnetic period (3,0 h) with the inductivity of geomagnetic field at 5×10 −8 Tesla caused the intensification of antiepileptic effects of EHF (15,0 min of exposure). It was pronounced in the form of decrease of foci intensity and significant reduction of lifespan of foci — up to 115,3±13,4 minutes, which was both significant when compared with separate effects of hypogeomagnetic influence (187,3±12,5 min) and EHF (15,0 minutes of exposure) effect (164,2±12,5 minutes) (P
