主 题：In this letter neuronal projections between the toad (Bufo bufo gargarizans) optic toctum and nucleus isthmi (NI) are studied by means of horseradish peroxidase (HRP) method and HRP-labeled tectal and isthmic cells are classified.After surgical operation the animal was fixed in a stereotaxic apparatus. HRP (Sigma VI) was iontophorezed into different sites over superficial layers of the tectum in 53 toads and throughout NI in 13 toads one injection each animal. After their survival of 2—8 days at 16—20℃ using HRP histochemical method the injected and labeled sites as well as the morphology of the labeled cells were shown.The results indicate that reciprocally topographic projections exist between the toad optictectum and its ipsilateral NI i. e. an isthmic
