In the developing nervous system, the basal plate is the region of the neural tube ventral to the sulcus limitans. It extends from the rostral mesencephalon to the end of the spinal cord and contains primarily motor neurons, whereas neurons found in the alar plate are primarily associated with sensory functions. The cell types of the basal plate include lower motor neurons and four types of interneuron.
Initially, the left and right sides of the basal plate are continuous, but during neurulation they become separated by the floor plate, and this process is directed by the notochord. Differentiation of neurons in the basal plate is under the influence of the protein Sonic hedgehog released by ventralizing structures, such as the notochord and floor plate.

La moelle spinale (selon la nouvelle nomenclature), ou moelle épinière (dans l’ancienne nomenclature), désigne la partie du système nerveux central qui prolonge la moelle allongée appartenant au tronc cérébral. Elle est contenue dans le canal rachidien (canal formé par la superposition des foramens vertébraux), qui la soutient et la protège. Elle est constituée de neurones et de cellules gliales. Sa fonction principale est la transmission des messages nerveux entre le cerveau et le reste du corps.

La neurulation est une étape du développement embryonnaire des métazoaires triploblastiques au cours de laquelle se met en place le système nerveux central. Elle succède à la gastrulation. La neurulation se déroule en 2 étapes : la neurulation primaire et la neurulation secondaire. La neurulation primaire comporte : la neuralisation : apparition de la plaque neurale par façonnage du neuroépithélium courbure et invagination fusion des bourrelets et fermeture du tube neural migration La neurulation secondaire est « caudale ».
Couvre le processus de gastrulation et le développement de plaques neurales pour la formation du système nerveux.
Explore les stades du neurodéveloppement, de l'induction au développement du cerveau postnatal, couvrant la régionalisation des plaques neurales, la fermeture des tubes neuraux et l'engagement du destin.
Explore le développement d'embryons animaux, en se concentrant sur les cellules souches et les applications d'ingénierie tissulaire.
