  • An essential role of SVZ progenitors in cortical folding in gyrencephalic mammals

    Toda Tomohisa , Shinmyo Yohei , Dinh Duong Tung Anh , Masuda Kosuke , Kawasaki Hiroshi

    … Although it has been proposed that increased neural progenitors in the subventricular zone (SVZ) are responsible for making cortical folds, their roles in cortical folding are still largely unclear, mainly because genetic methods for gyrencephalic mammals had been poorly available. … Here, by taking an advantage of our newly developed in utero electroporation technique for the gyrencephalic brain of ferrets, we investigated the role of SVZ progenitors in cortical folding. …
