抄録

After removing the parts of each motor area of fore-limb, hind-limb, both areas of them and mixed area of both-limbs, the degeneration of the nerve fibres was pursued by Marchi staining. There were found not only the efferent fibres coming directly down, but also those taking roundabout way from these each of the fore- and hind-limb (all of the latter had been considered as associating fibres up to the present) and thus it was illustrated that they were intricating. These fibres included the pyramidal tract as well as the extrapyramidal tract. When the investigation was performed till the end of the spinal cord, it was found that the area for the hind-limb included a part of the fibres reaching the fore-limb.
