Effects of reciprocal forebrain transplantation on motility and hatching in chick and duck embryos. 1976

G S Sohal

Effects of reciprocal forebrain transplantation on the embryonic motility and the hatching behavior in the chick and the duck embryos were studied. The forebrains were transplanted before the establishment of circulation. The grafted tissue formed the telencephalon, diencephalon, eyes, upper beak and part of the cranium. Data indicate that the size of the forebrain has no significant influence on the early embryonic motility (Type I and II) in the chick and the duck embryos. The initiation and maintenance of the pre-hatching behavior (Type III motility) does not reside in the forebrain. The final stage of hatching (climax) on the other hand may be controlled by the forebrain.

UI	MeSH Term	Description	Entries
D009043	Motor Activity	Body movements of a human or an animal as a behavioral phenomenon.	Activities, Motor,Activity, Motor,Motor Activities
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
D004027	Diencephalon	The paired caudal parts of the PROSENCEPHALON from which the THALAMUS; HYPOTHALAMUS; EPITHALAMUS; and SUBTHALAMUS are derived.	Interbrain,Interbrains
D004372	Ducks	A water bird in the order Anseriformes (subfamily Anatinae (true ducks)) with a broad blunt bill, short legs, webbed feet, and a waddling gait.	Duck
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.
