a previous study that used high-resolution video ( vec-dic ) microscopy to examine axonal growth cones of aplysia giant neurons growing in culture had demonstrated that growth occurs by the extension of veils of membrane between filopodia and the subsequent morphological transformation of these veils , in place , into the swollen , organelle-filled central region of the growth cone and then into the cylindrical axon .
