- Abstract
Type II focal cortical dysplasias (FCD II) are highly epileptogenic brain lesions characterized by severe cortical dyslamination and by the presence of abnormal giant cells defined as dysmorphic neurons and balloon cells (typical of FCD IIb). Why are type II focal cortical dysplasias frequently located at the bottom of sulcus? MRI abnormalities predominate in the bottom part of the sulcus with type II focal cortical dysplasia: a quantitative study. However, since the size of the developmental lesion has been correlated with the timing of the insult, it is likely that in more extensive non-BOSD dysplasias a higher number of cells with hyperactive mTOR signaling will be responsible for the more severe disruption.27 Finally, the present hypothesis is based mainly on the pathogenic role of bRGCs on brain development and folding.
