Histopathological identification of subtle cortical architectural abnormalities in focal cortical dysplasia (FCD) resections remains challenging. We investigated if artificial intelligence (AI)‐based morphometric and spatial analysis of NeuN‐stained cortical sections could detect neuronal architectural disorganization in epilepsy resections, including ...
