[Influence of transcranial electromagnetic brain stimulation on development of conditioned reflex in rats].

The influence of transcranial electromagnetic stimulation on the development of an active avoidance reflex with painful reinforcement in laboratory rats is investigated. It is shown, that an exposure of the rats' brain to electromagnetic radiation in the millimeter range ((λ = 5,6 and 7,1 mm), modulated as a series of low-frequency pulses, leads to a suppression of the development of the conditioned avoidance reflex occurred in 50% of cases. In other 25% of cases irradiation leads to inhibition of reflex development.
