Neural induction

Neural Induction

the process by which a biological entity (e.g., cell, tissue) undergoes a change in state under the influence of an inducing stimulus (e.g., a molecule presented by another cell or tissue)

gastrulation

Cell movements in the early embryo that result in the formation of three distinct germ layers. it is also when neural induction occurs

what 3 germ layers are established during gastrulation?

endoderm → ectoderm → mesoderm

what do BMPs do?

inhibit a default neuronal fate in the animal pole

notchchord

A transient, specialized mesodermal derivative that induces the formation of neural ectoderm (the neural plate) and will later be important for dorsal-ventral patterning signals.

gastrulation & neurulation (frog embryo) all together

the invagination of the blastopore results in translocation of the presumptive mesoderm (including the notochord) derived from the border of ectoderm adn endoderm
