Ion channel Dysfunction Associated with Prenatal Diseases
Ion channel Dysfunction Associated with Prenatal Diseases
Timeline of human gestation from early cortical formation, including key developmental cellular processes and milestones, highlighting the development of abundant action potentials in the cerebral cortex . Bottom, ion channel genes (ATP1A3, SCN3A, GRIN1, and GRIN2B) implicated in cortical malformations (MCDs) all maintain high expression in the developing human cortex . The specified genes are representative and are not a comprehensive list.

"Folded" Ferret brain model of human cortex development
Ferret neocortex recapitulates human disease (unpublished from microcephaly cases), a disease not able to me modeled in mice with smooth brains (lysencephalic).
