Histogenesis of the cochlear nucleus of the mouse.

摘要: In Nissl-stained preparations of the cochlear nucleus there are nine recognizable cell types. These cells born during three periods histogenesis prenatally. On gestation days 10.0, 10.5, and 11.0 pyramidal, giant, dark-staining born. The spherical, globular, multipolar, horizontal formed on 12.0, 12.5, 13.0 small follow day 14.5. onset granule formation is 14.5 continues to birth 19. At birth, for at least first 2 postnatal weeks, glial There no regional gradients in dates, from all dates being intermixed. Cell proceeds an orderly sequence that related only size. Although were apparent spatiotemporal patterns, some clustering labeled was evident. observations do not support hypothesis Golgi Type I precede II their order since both large neurons project beyond nucleus. is, nonetheless, a sequential pattern auditory system, with preceding neurons.
