Introduction
Mark Hill (talk) 11:37, 15 May 2017 (AEST) New lecture under development - this notice removed when completed. Begin your background reading by looking at the textbook links.
Neural development is a complex and ongoing process that commences in week 3 and continues through into the postnatal period. This lecture will introduce concepts about the timing, origin and abnormalities of the nervous system. Lecture content will be added to this current page, the linked online textbook chapters are available as pre-reading for this lecture.
The human MRI movie below (head, sagittal plane, left to right) shows the central nervous system (CNS) development at the end of the embryonic period (week 8; GA week 10).
