Glycine-immunoreactive synapses in the central nucleus of the inferior colliculus. An electron microscopic study in
1Department of Anatomy, Shiga University of Medical Science, Otsu, Japan.
Abstract:
It has been known that the inferior colliculus contains many glycinergic fibers of both intrinsic and extrinsic nature. In the present study, glycine-immunoreactive (Gly-ir) synapses were examined in the central nucleus of the inferior colliculus in the cat. About half of 891 axondendritic synapses that were identified in the present study were Gly-ir. In 75% of these Gly-ir synapses, synaptic axon terminals contained pleomorphic or flattened synaptic vesicles and made symmetric synapses, while in 25% of Gly-ir synapses, synaptic axon terminals were filled with spherical synaptic vesicles and formed asymmetric synapses. Thus, Gly-immunoreactivity was detected in axodendritic synapses that formed both Gray's type I and Gray's type II synapses.
