This image shows the spine in which I hope to incorporate a lighting system. 

This lighting system will include  different colours representing the various messages moving back and forth to the brain.

This will be a visual depiction of what happens within the human body. 

These components will be made from poly carbon so that they can be visible throughout.

A linking mechanism will also be made from poly carbonate which will allow the wires necessary for LED to be transferred through them.  Again they will be visible throughout.
