| Outline of Final Research Achievements |
The present study revealed the presence of a neural pathway: retina-optic tectum-nucleus prethalamicus-dorsal telencephalon. The morphology of the tecto-prethalamic neurons was investigated in detail, since the optic tectum not only receive visual information but also other sensory modalities including lateral line, auditory, somatosensory information. Dendritic arborization of tecto-prethalamic neurons extends to tectal layers where retinal fibers terminate, indicating that the above-mentioned pathway represents an ascending visual pathway to the telenecephalon.
Searches on the visual centers by the use of neural activity markers gave preliminary results, and further studies will be continued.
