[The influence of hypogeomagnetic field on bioelectric activity of the brain in epilepsy].

An influence of geomagnetic field (GMF) on bioelectric activity of the brain was studied in 20 epileptic patients by the use of "hat", which attenuated GMF. A short-term attenuated GMF increased a EEG synchronisation by alpha-rhythm, generalized slow-waves discharges. Some similarities and differences were found in attenuated GMF effects and in the results of hyperventilation trial. The main role in perception of attenuated GMF belongs to the parietal area of the right hemisphere.
