Proposed model of cortical oligodendrogenesis. a Ventral oligodendrogenesis is dependent on Shh signaling. Shh-independent generation of oligodendrocyte precursor cells (OPCs) occurs at the lateral and medial dorsoventral boundary, where FGF signaling may overcome the suppression of oligodendrogenesis by Wnt signaling. b The origins of the dorsal-most portion of the adult cortex remain to be determined
