The germinal matrix is the source of both neurons and glial cells and is most active between 8 and 28 weeks gestation.
Location/anatomy: The germinal matrix is next to the lateral ventricles (the "inside" of the brain).
Function/physiology: Neurons and glia migrate radially outward from the germinal matrix towards the cerebral cortex.
[1][2][3] Dysfunction/pathophysiology: in prenatology/neonatology, intraventricular hemorrhages occur starting in the germinal matrix due to the lack of structural integrity there.
Intraventricular hemorrhages are a common and harmful issue in children born prematurely.
