(FRAME-INFO (STRING "Brainstem Nuclei.  The development of the fourth ventricle causes the displacement of the alar plate from a dorsal position to a more lateral position, but the general rule still holds: the alar plate gives rise to sensory structures \(for example: section A, the gracile and cuneate nuclei; section B*, the solitary and cochlear nuclei\) and the basal plate to motor structures \(for example: section B*  the hypoglossal and vagal motor nuclei\). In addition, the alar plate gives rise to the cerebellum, the inferior olivary nucleus, the substantia nigra and the nucleus of the superior colliculus.  Section B* is at the same level as B, but at a later stage of development."))
