Glycine-like immunoreactive (LI) axon terminals were observed on large ventral horn cells by the indirect antibody peroxidaseantiperoxidase technique in the chicken. The glycine-LI terminals were also confirmed on identified a-motoneurons by retrograde transport of horseradish peroxidase (HRP). Electron microscopically, glycine-LI terminals containing pleomorphic clear vesicles made axosomatic and axodendritic synapses with large ventral horn cells including identified a-motoneurons. They formed mostly symmetrical synapses, but a few asymmetrical synapses were also seen. These glycine-LI terminals contained numerous mitochondria. The number of boutons per perimeter of a large ventral horn cell was 0.15±0.05/μm (n=90). The results indicate that α-motoneurons receive glycinergic inputs. The origin of glycinergic inputs is discussed in the light of previous investigations.
