Regional variations of choline-acetyltransferase in the chick embryo optic lobe. 1976

G Teitelman, and M J de Asua

The specific activity of CAT and AChE was determined in different regions of the chick embryo optic lobe at several stages of development. Regional differences in CAT activity appeared in 9-day-old tectum, being the posterobasal area the one with higher enzymatic activity. On the other hand, at 6th and 13th day of development, the levels of AChE and CAT are similar throughout the optic lobe.

D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick

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.
