Medical 3D Model. Human Brain, nerve cells

Create a 3D model of the nervous system, especially the brain. It is definitely not necessary to show all kind of nerves, but to simplify and to visualize the effects of multiple sclerosis. They effect a certain kind of neurons, see below.

The model will be used for fly through animation.

The show will be a fulldome show, which we'll screen in planetariums and

The brain we should think of could look similar to this:

Only, what happens in there is not exact enough. Maybe it could look like this:

The main nerve cell we are talking about looks like this:
