In teleosts the optic tectum is the major integrative centre in the brain. The cyto- and fibre architecture of the optic tectum have been studied extensively and a well-defined laminar pattern has been described. Here some aspects of the fine structure of the optic tectum of the goldfish, Carassius auratus, will be described and discussed. Goldfish which had been kept at a temperature of 15°C were fixed by perfusion with 2. 5% glutaraldehyde in a phosphate buffer. After fixation pieces of the optic tectum from both dorsal and ventral regions, cut so that their original orientation in the tectum could be determined by their shape, were removed. They were post-fixed in 1% osmium tetroxide in the same buffer for 1 1/2 h, dehydrated, stained in 2% uranyl acetate and embedded in epon. Sections were stained with lead citrate.Lining the ventrical is the ependyma consisting of epithelial-like cells which are 5. 4 μm in diameter, are ciliated, and joined by both desmosomes and tight junctions between their somata.
