Using a Mind Map to Explore a Potential Research Topic

It is still early days but I've been working on a potential PhD research topic. To do this, I approached it the same way I did my Masters by Research - using a mind map. There some great applications to to do this and I chose a program called Prezi that I downloaded onto my iPad.
See below my prezi that I have been working on;

I still have approximately six months to define and refine my research topic. But I find the best place to start is to just get all your ideas out of your head and into a visual space.
