The Author researched the Conduction Pathways of Epileptic Convulsion on dogs by Marchi method. The results were as follows: 1. The descending fibers from the areas 4a, b of the cerebral cortex reach the homolateral lentiform nucleus and other neurons reach the lateral and ventral nuclei of the homolateral thalamus. The neurons moreover reach in the head and tail of the homolateral caudate nucleus. 2. The caudate nucleus and the lenticular nucleus are connected closely with the numerous fiber bundles crossing the internal capsule. 3. The fibers from the lenticular nuculeus descend through the lenticular fasciculus and Ansa lenticularis and reach the homolateral substantia nigra. The other neurons connect with Corpus Luysi, nucleus ruber, Cajal's interstitial nucleus, Darkschewitsch's nucleus, Westphal-Edinger's nucleus, oculomotor nucleus, and superior colliculus. 4. The descending fibers from the substantia nigra reaching the homolateral pyramis, fascicullus praedorsalis, fibrae arcuatae lateralis, nucleus funiculi lateralis are recognized. These fibers pass the Decussatio pyramidum, run down in the Funiculus lateral and reach the nucleus anterior spinalis. 5. The ascending fibers from the cerebellar cortex (lobus lunatus anterior, lobus lunatus inferior, lobus semilunaris superior, lobus semilunaris inferior) reach the dentate nucleus and pass through the brachium conjunctivum to reach the contralateral ventral nucleus of the thalamus and then connect with the descending pathways from the cerebral cortex. 6. The communication between both cerebellar hemispheres and thalami are revealed.
