[Participation of monoaminergic mechanisms and the striatum in the development of "petit mal" induced by corazole].
In gradual cumulation of subconvulsive doses of corasole in mice there are certain changes of behaviour and electrographical signs which are close to "petit mal": slow negative waves and peak-wave complexes on the EEG, myoclonic jerks. An increase of monoaminergic transmission of apomorphine, DOPA, or 5--hydroxyhyptophane weakens the preconvulsive effect of corasol, while its inhibition by aminasine, haloperidol and p-chlorphenylalanine on the contrary increases it. A low frequency electric stimulation of the striatum potentiates the expressiveness of corasole "petit mal", while its destruction limits it. A bilateral destruction of the striatum eliminates the action of apomorphine, DOPA and haloperidol but only slightly changes the effect of aminazine, 5-hydroxytryptophane and p-chlorphenylalanine.
