EXPERIMENTAL STUDIES ON THE CEREBELLAR SEIZURES
PART 2. EXPERIMENTS ON THE CONDUCTION OF THE CEREBELLAR CONVULSIVE SEIZURES

In the 1st report I concluded that epileptic seizure was induclable in the cerebellum. So this time in order to study the pathway of the convulsion, I cut or deslroyed the various parts of the rabbit's brain, and observed the changes of the threshold of cerebellar seizure and convulsive pattern.
Assuming that the threshold increased in consequence of partial intersectron of the pathways. the convulsive pathways are as follows.
1. From the hemisphere
a) The principal pathway ; Cross after passing through the homolateral superior cerebellar peduncle, and descends after reaching the midbrain (principally in the red nucleus) and diencephalon partially.
b) The other pathway; Cross in the cerebellum, and desends after passing through the contrateral inferior cerebellar peduncIe.
2. From the vermis
a) Three pathways ; After passing through the homolateral superior cerebellar peduncle, one reaches the red nucleus leveI of the contalateral midbrain, one descends immediately after crossing at the caudal part of the midbraain, and the last one reaches the red nucleus level of the homolateral midbrain.
b) Two pathways ; One via the homolateral and the other via the contralateal inferior cerebellar peduncle, reach the pons and medulla oblongata, and then desend.
