Welcome to Brain Development

width=320px|height=260px|controller=false|autoplay=true</qt> 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

Here is a developing mouse nervous system

This movie shows a mouse 11.5 days old.

(Mouse development takes 21 days)


Red - brain



Blue - heart



Brown - liver

Quicktime


This embryo is the whole human embryo at just 3 weeks after fertilisation.

  • the entire nervous system will form from the flat region shown in blue.
    • this is called the NEURAL PLATE.


  • the broad blue region at the top will form the brain.
  • the narrow blue region at the bottom will form the spinal cord.

That folds to a Tube

The tube then Closes at the Ends
