@article{2552, abstract = {The superficial layers of the superior colliculus (SC) have been known to contain many axons showing substance P-like immunoreactivity (SP-LI). We, therefore, immunohistochemically examined the distribution of SP receptor (SPR) in the superficial layers of the SC in the rat by using a specific antibody against SPR. The majority of SC neurons with SPR-LI were distributed in the zonal and the superficial gray layers, the rest of them were in the optic layer. Electron microscopy revealed that SPR-immunoreaction products in SC neurons were distributed not only in postsynaptic sites, but also in non-synaptic regions of perikaryal and dendritic profiles.}, author = {Ogawa Meguro, Reiko and Shigemoto, Ryuichi and Itoh, Kazuo and Konishi, Akira and Mizuno, Noboru}, issn = {0304-3940}, journal = {Neuroscience Letters}, number = {2}, pages = {135 -- 138}, publisher = {Elsevier}, title = {{Immunohistochemical localization of substance P receptor in the superior colliculus.
