Ultrastructural localization of acetylcholinesterase in retino-deprived optic tectum of the goldfish. 1979

A Contestabile, and F Ciani, and L Villani

The ultrastructural localization of AChE has been studied in the optic tectum of the goldfish after unilateral eye ablation. 1 or 4 months after the operation the patterns of enzyme localization were essentially the same in the normal and affected optic tectum, despite structural modifications caused by the degeneration of retinal terminals and dendritic atrophy of some tectal neurons. The results are discussed in relation to the different hypotheses put forward concerning possible cholinergic mechanisms in the optic tectum of teleosts.

UI MeSH Term Description Entries
D012160 Retina The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent. Ora Serrata
D006054 Goldfish Common name for Carassius auratus, a type of carp (CARPS). Carassius auratus
D000110 Acetylcholinesterase An enzyme that catalyzes the hydrolysis of ACETYLCHOLINE to CHOLINE and acetate. In the CNS, this enzyme plays a role in the function of peripheral neuromuscular junctions. EC 3.1.1.7. Acetylcholine Hydrolase,Acetylthiocholinesterase,Hydrolase, Acetylcholine
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
