Figure 3. Summary of the Present Study (IMAGE) Kanazawa University Caption Schematic illustration of the cerebral cortex, a sectional view. Among regions of the cerebral cortex, those where a large number of neural progenitors exist would develop gyrus formation (left). By inhibiting FGF signaling, neural progenitors are reduced and gyrus formation is impaired (right), indicating FGF signaling is important for gyrus formation.
