[The trigger role of the left cerebral hemisphere in generalizing epileptic activity].

Overall 593 epileptic patients with left hemispheral lateralization of the focus and 46 patients with primary generalized epilepsy were examined. EEG and computerized mapping of cortical biopotentials were used. It has been shown that in right-handed patients, the left hemisphere triggers epileptogenesis whatever the site of the source of epileptic activity. The mechanism by which epileptogenesis is triggered includes the posterotemporal and central cortical areas of the left hemisphere.
