A smooth brain malformation of the CEREBRAL CORTEX resulting from the abnormal location
of developing neurons during corticogenesis. It is characterized by an absence of
normal convoluted indentations on the surface of the brain (agyria), or fewer and
shallower indentations (pachygryia). There is a reduced number of cortical layers,
typically 4 instead of 6, resulting in a thickened cortex, and reduced cerebral white
matter that is a reversal of the normal ratio of cerebral white matter to cortex
