[The demonstration of recurrent motor axon collaterals in the chick embryo by using horseradish peroxidase axonal transport].
Motoneurons were labelled by retrograde axonal transport of HRP applied to transected spinal nerves in 9-11-day chick embryos in the in vitro spinal cord preparation. Recurrent motor axon collaterals were revealed in 17 of 48 motor axons which could be followed in the edge regions of labelled motoneuronal pools. The results, coupled with author's earlier electrophysiological data, provide further evidence for the presence of the Renshaw inhibition in the avian spinal cord.
