Olfactory sensitivity to bile acids in salmonid fishes.

摘要: Monopolar DC-recordings were made simultaneously from two positions on the olfactory bulb of chars (Salmo alpinus L.) and graylings (Thymallus thymallu using bile acids amino as stimulants. The induced responses with characteristic spatial differences those acids. distribution to indicated a neuronal activity in medial part bulb. In contrast, elicit lateral Taurine conjugated up 1 000 times more potent stimuli than methionine. results suggest that receptors are types, one responding acids, other 3 -alpha-hydroxysteroids released fish into water quantities suffice for detection by their system. odorant potency evolutionary history variability, together renowned adherent properties them interesting candidates specific signals acquatic environment.
