Figure 2

The rodent ventral and dorsal telencephalon. The left side of the figure is the rodent ventral telencephalon. The right side of the figure is the rodent dorsal telencephalon. In the ventral telencephalon, the Ascl1 gene (LGE, MGE) is expressed. Glial progenitors and oligodendrocyte precursor cells (OPCs) induce the expression of Olig1/2. In the dorsal telencephalon, the cortical progenitors induce the development of the neocortex and the expression of Neurog1 and Neurog2 (VZ). The mature neurons induce the expression of NeuroD genes, such as NeuroD1 (SVZ), NeuroD2, and NeuroD6 (cortex).
