Substance P-like immunoreactive retinal terminals found in two retinorecipient areas of the Japanese monkey.
Using peroxidase-antiperoxidase immunocytochemistry, we demonstrated a dense accumulation of substance P-like (SP) immunoreactive terminals in the internal layer of the pregeniculate nucleus and in the pretectal olivary nucleus of the Japanese monkey. These distributions of immunostaining were similar to those for retinofugal terminals in the same nuclei. Bilateral eye enucleation markedly decreased SP immunoreactivity in the nuclei. The reduced immunoreactivity probably reflected the loss of SP-containing retinal ganglion cells that sent axons to the pregeniculate and pretectal olivary nuclei.
