Figure 12:  Sequence of myelinization from the 1933 paper by Langworthy.  Note:
(1) At fetal age 24 myelinization in the cochlear nerve (VIII) and acoustic lemniscus,
(2) At fetal age 28 in the acoustic colliculus, and
(3) Tracts from pons to frontal and temporal lobes beginning after 8 postnatal weeks.
