Abstract:
The glomerular synapses of the substantia gelatinosa in the spinal trigeminal nucleus of the rat were examined by electron microscopy. The central axonal ending in the glomcruli forms asymmetrical axodendritic synapses on adjacent type 1 and type 2 dendrites. Type 2 dendritic spines or shafts (dendrites which contain synaptic vesicles) form dendrodendritic synapses on Type 1 dendritic spine or shafts (dendrites without synaptic vesicles) and also form dendroaxonic synapses on the central ending. The peripheral terminals (P) form symmetrical axoaxonic synapses on the central ending and form axodendritic synapses on the dendrites in the glomeruli.
