EXPERIMENTAL STUDIES OF EPILEPTIC SEIZURE ON THE BASIS OF "MARCH OF MOVEMENT"
Ⅲ. SPREADING MODE OF CONVULSION BY THE STIMULATION OF SUBCORTICAL NUCLEI.

Studies have been made on subcortical nucIei which are considered to be closely related to the development of convulsion.
Both the nucIeus Ientiformis and thalamus produce convulsion of the contralateral limb. Stimulation on the midbrain produces a special type of convulsion, which developes and ceases simultaneously in the extermities. In this paper this type of convulson is designatd as "homophasic convulsive seizure". Stimulation on the midbrain, after ablation of the bilateral motor areas, produces a homophasic convulsion, proIonging contraction time and relaxing time, accompanied by pronounced rigidity. It is also the case with midbrain animals.
Thus it is assumed that a homophasic convulsive seizure is produced by excitation of the midbrain. Namely, the homophasic convulsive seizure produced by strong stimulation of the cortex must be the product of secondary excitation of the midbrain.
