[Influence of the brain stem reticular formation on seizure activity in the cerebral cortex].
Activation of the mesencephalic RF facilitates triggering of paroxysmal potentials and augments existing epileptic activity. Stimulation of nucleus reticularis pontis caudalis inhibits triggering of epileptic discharges. The microelectrode studies corroborated these data. The desynchronization elicited by the mesencephalic RF seems to be mostly activating, whereas desynchronization elicited by the nucleus reticularis pontis caudalis--mostly inhibitory.
