    Abstract:
    On the basis of simultaneous measurement of the rheosubcorticogram, polarogram, intracerebral pressure (ICP), ECoG and subcorticogram in patients with electrodes and sensors implanted in the brain, it was established that with the development of the seizure a rapidly reversible growth in the amplitude of deep rheoencephalogram, pO2 and ICP occurs beginning from the subclinical phase of epileptogenesis augmentation. According to the findings of deep rheoencephalography, the values of the tonic-elastic properties of the cerebral vessels undergo two-phase changes with the development of stable vasoparesis. The results of the study show that reactive hyperemia of the brain is the cause of the increased ICP; the cerebral perfusion pressure decreases in this case. A close correlation has been established between the values that were studied, particularly in the period of post-seizure coma.
