'Dendraxons' in regenerating motoneurons in the cat: do dendrites generate new axons after central axotomy?
The intramedullary portions of motor axons in the spinal cord of adult cats were divided by longitudinal incisions in the ventral funiculus. After 7-11 weeks ventral horn neurons were injected intracellularly with horseradish peroxidase. Regenerating processes of the injected cells were studied with light- and electron-microscopical techniques. The results show that in some cases more than one axon-like myelinated regenerating process was found in a single neuron. Moreover, in such cases at least one of the processes seemed to be of dendritic origin.
