Abstract
Background: The mammalian cerebrum has changed substantially during evolution. Neurons and glial cells have increased, and the cerebrum has expanded and folded. Although these evolutionary changes are believed to be important for acquiring higher cognitive functions, the molecular mechanisms underlying the development and evolution of the mammalian cerebrum are not fully understood. This is partially due to the difficulty in analyzing these mechanisms using only mice. Summary: To overcome this limitation, we developed genetic manipulation techniques for the cerebrum of gyrencephalic carnivore ferrets. Gene knockout in the ferret cerebrum was achieved using the CRISPR/Cas9 system. Key Messages: This review highlights recent research from our lab and others on the mechanisms underlying the development and evolution of cortical folds using ferrets.Keywords
