Feinstruktur des Bulbus olf actorius des Haushuhnes

Abstract

I n order to investigate the fine structure of the didten's Bulbus olfactorius a n d to determine differences between birds and mammals, tissue specimen were taken from 26 animals. The following techniques were used: Luxol-Fast-Blue-a n d Nisslstaining, Bodian impregnation. Marked differences between the Bulbus of chidten a n d mammals were found lightmicroscopically in the number of the cell layers and the localization and size of cells.The electronmicroscope revealed that the cell organelles a n d the different types of synapses resembled the ones found in mammals. The mitral cells of the hen contrary to the ones of mammals often contained lamellar bodies.
