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).

Aim
To develop an understanding of the development of the nervous system and the consequences of abnormal development.
Draft Lecture Timetable - Monday 29 May 2017 09:00 AM - 10:00 AM Development of the nervous system Kensington - Rex Vowels Theatre

Week 3 - Neural Plate
Ectoderm
- neural plate - midline (columnar cells)
- neural crest - outside lateral edges of neural plate
- surface ectoderm - lateral (cuboidal cells)
- head - sensory and anterior pituitary (placodes)
- integument - epidermis of skin, hair, glands, teeth enamel
Neural Plate
- extends from buccopharyngeal membrane (oral membrane) to primitive node (Hensen's node)
- forms above notochord and paraxial mesoderm
- neuroectodermal cells - neural plate, neural crest
- rostrocaudal width
- brain plate (broad)
- spinal cord (narrow)
