Distribution of gycine-immunopositive neurons in the visual center of the hamster was studied by immunocytochemical technique, quantitative analysis was made statistically. The results showed that except the layerⅠ,the glycine-immunopositive neurons are distributed through all layers of the visual cortex. The mean density is 1 046/mm². An average of 23.9% of the neurons in visual cortex is immunopositive for glycine. The densities of positive glycine neurons in the superficial stratum and deep stratum of superior collicular are 750/mm² and 781/mm² respectivelly and their percentage are 19.5% in superficial layer and 20.3% in deep layer. Glycine-immunopositive neurons of visual center include different type of cells.
