[The mechanisms of the occurrence and development of the epileptic range of disorders]

An attempt was made to approach to the causes of the development of epileptic disorders from general biologic positions and to determine the signs of a normal organism, that might help to predict a risk of the disease manifestation. A pattern of electric activity of the brain of the animals, both sensitive and resistant to convulsive agents' action in terms of the influence of convulsive and anticonvulsive preparations on EEG are presented. A role of the brain's mass and of the peculiarities of dermatoglyphics as the predictors of the development of epileptic disorders are also discussed.
