So what the noticore does is it stimulates the outward motion, the outward movement, the imagination of the neural plate of this section here towards the noticord. And what we begin to produce is something called the neural groove. And these two folds we call the neural fold. So these are the two neural folds. And this is a neural groove that is produced as a result of that outward motion of this central portion of the neural plate. Now the continual outward motion of that neural plate eventually brings these two neural folds together.
