Indirect short-term influences of alternating magnetic fields on the brain in epilepsy

Changes the bioelectrical activity of the cerebral hemispheres were studied in 20 patients with epilepsy and 18 healthy subjects subjected to local alternating magnetic fields (MF) applied to the hand. MF produced increases in epileptic activity in terms of the bioelectrical characteristics of foci and the level of generalization. This suggests that alternating MF can be used to identify the localization of epileptic foci. The most stable changes in response to alternating MF were seen in the posterior parietal parts of the right hemisphere. It is concluded that the effects of alternating MF are produced mainly by processes in the right hemisphere.
