            Telencefalon je najpromenljivija struktura mozga riba i razlikuje se od vrste do vrste. Studija predstavlja pokušaj da se ispita ćelijska struktura telencefalona Scyliorhinus canicula. Identifikacija telencefaličnih jedara vršena je na preparatima obojenim metodima Nissla i Golgi. Na osnovu veličine i oblika neuronskog tijela i njihovih nastavaka, analizirano je više od 300 nervnih ćelija. Nervne ćelije u telencefalonu se razlikuju znatno po : veličini i obliku neuronskog tijela, dendritskoj arborizaciji i dendritskom polju prostiranja. Specifičan je aranžman neurona u određenim strukturama.

Ključne riječi: Scyliorhinus canicula, telencefalon, nervne ćelije.

GOLGI STUDY OF TELENCEPHALON IN  SCYLIORHINUS CANICULA

 

            The telencephalon is the most variable structure of the fish brain and it differs from species to species. This study represents an attempt to investigate the cellular structure in telencephalon of Scyliorhinus canicula. Identification of telencephalic nuclei in Scyliorhinus canicula was based on Nissl and Golgi methods. More then 300 cells have been examined on the basis of size and shape of the neuronal body and their processes. The nerve cells in the telencephalon differ considerably in size of cell bodies, their dendritic arborization and dendritic field radius. There is a specific arrangement of neurons in certain structures.

Key words: Scyliorhinus canicula, telencephalon, nerve cells.
