In today's demonstration we will be looking at how the brain develops from a simple tube into the complex folded structure you will be seeing (and using) today. This animation shows a real human adult brain being "sliced", the cortex (grey matter) is on the outside.

Here is Human Development

Here is how the human nervous system grows

3 Dimensional Reconstruction Based upon a serial reconstruction from individual embryo slice images. (6 mm pig embryo, approximately Human day 32, Carnegie Stage 13/14 embryo) The ectoderm contributes the neural tube structures of the central nervous system. Below the animation is a more complete description of this system.
