Cortical resection for intractable epilepsy demonstrated International League Against Epilepsy (ILAE) Type IIb focal cortical dysplasia characterized by the presence of dysmorphic and balloon neurons (Figures 2C and 2D) that were further variably highlighted by glial fibrillary acidic protein (GFAP), synaptophysin, and neuronal nuclei (NeuN) immunostainings (Figures 2E–2G). Here, SYP is linked to cerebral cortical dysplasia.
