Where does craniocaudal closure of anterior neuropore start?
Where is this second craniocaudal wave originating?


It begins in the prosencephalic region adjacent to the chiasmatic plate.


  Where is the final point of meeting (I suspect linea terminalis or anterior commissure) ?


Cranial linea terminalis represents the zone of closure of cranial neuropore.


  Could anyone post a picture or a reference to understand this visually (both waves of neurulation)?
