Perinatal Cerebellar Injury in Human and Animal Models

Figure 3

Summary of the main morphogenetic and histogenetic events during development of the human cerebellum from the ninth gestational week (wks) to the seventh postnatal month (p.n.m.) shown in sagittal plane at the level of the primary fissure. E: ependyma, EG: external granular layer, G: Granular layer, I: intermediate layer, L: laminar dissecans, M: molecular layer, P: Purkinje cell layer, V: ventricular zone. W: white matter. The 5 mm scale in the upper corner of the figure show the dramatic increase of the cerebellum primordium especially from the beginning of foliation to 16 wks to 7 pnm.
