nervous system , the basal plate is the region of theneural tube ventral to thesulcus limitans . It extends from the rostralmesencephalon to the end of thespinal cord and contains primarily motorneuron s, whereas neurons found in thealar plate are primarily associated with sensory functions. The cell types of the basal plate includelower motor neuron s and four types ofinterneuron .cite book | author=Bruce M.

neurulation they become separated by thefloor plate , a derivative of thenotochord . Differentiation of neurons in the basal plate is under the influence ofSonic hedgehog released by ventralizing structures such as the notochord and floor plate.References
