Abstract
Soon after closure, the cephalic end of the neural tube expands to form three primary vesicles, prosencephalon, mesencephalon and rhombencephalon. They are the progenitors of the forebrain, midbrain and hindbrain, respectively. The prosencephalon, during 4–10 weeks of gestation, develops by the process of ventral induction which includes formation, cleavage and midline development. Failure of formation results in aprosencephaly or atelencephaly. Total or partial failure of cleavage results in the spectrum of holoprosencephaly. Abnormal midline development results in agenesis of CC or septal agenesis. Holoprosencephaly is dealt with in Chap. 3. Anomalies of the CC and septum pellucidum will be described in this chapter.
