A single or rhythmical (1-3/sec) stimulation of the caudate nucleus in unrestrained rats facilitated formation of slow negative waves and the spike-wave complexes in the EEG of the sensory-motor cortex and contralateral neostriatum, as well as development of behavioral disturbances due to subseisure doses of pentylentetrazol. During the low-frequency stimulation of the caudate nucleus or after its cessation, when giving the convulsant drug, regular potentials of the spike-wave type or a general seizure may occur. The caudate nucleus is supposed to be able to participate in the petit mal seizure mechanisms because of its syndhronizing influences on the cortex.
