well formed, which is consistent with earlier normal embryogenesis of the telencephalon.
Bilateral occlusions of the internal carotid arteries in utero is a potential mechanism.
Clinical features include intact brainstem reflexes without evidence of higher cortical
activity. (Menkes, Textbook of Child Neurology, 5th ed, p307);
