GAP43 and cerebral cortical dysplasia: Since it has been recently shown that GAP‐43 upregulation induces excitatory but not inhibitory synaptogenesis in a rodent cortical dysplasia model,33 we performed immunofluorescence (Figure 5D‐F) and Western blot analyses of GAP‐43 content within the region adjacent to the malformations (Figure 5K).
