Separated immature RNm cells first appear around 12 weeks of gestation. They show up in clumps dorsal to the pavocellular red nucleus(RNp). The RNm then takes the shape of a crescent moon ventral to the RNp consisting of Basophilic neurons. 18 to 23 weeks into gestation the neurons then appear dorsal to the RNp, as island clusters among the myelinated oculomotor nerve roots. Around 28 weeks the nerves were distributed ventral and lateral to the superior cerebellar peduncle as well as around he caudal pole of RNp. As gestation progresses the neurons increase in size, fracturing into two distinct sizes, becoming clear at 33 weeks. In summary the differentiation and maturation of the RNm slowly progresses in the later half of gestation.
