[Significance of magnetic field parameters for altering brain evoked bioelectrical activity].
The effect of a constant uniform magnetic field of 0.1 to 1.6 T on the somatosensory potentials of the brain cortex and hypothalamus was investigated on nembutal anesthesized rats. The exposure increased the amplitude and modified the form of evoked potentials in both brain structures. The effect grew significantly with induction of the magnetic field. At every induction level changes in the evoked potentials of the hypothalamus were more distinct than those of the cortex. These findings were compared with the effects of a weakly pulsating magnetic field of the induction 0.1-0.4 T.
