In larval lampreys (body length 30–80 mm), the central projection of VIII nerve afferents was traced with selective silver methods for degenerating axoplasm. In 30–40 mm animals, lateral regions, described by Rudeberg as ''migration A'', are filled with degenerated terminals. In 50–80 mm animals, the ipsilateral nucleus intermedialis and nucleus cerebelli are so filled. These regions are the adult derivatives of ''migration A'', suggesting the maintenance of functional connections during neural development.
