Advice on neuroscience competition?

Hey guys, so I was interested in entering the AAN http://tools.aan.com/science/awards/?fuseaction=mobile.info&id=11 (American academy of neurology.) I’m just confused on how this works, yes I looked on the website. For the research do you have to work with a professor in a lab? If this is the case how do you get a professor to work with you? I really want to be a neurologist, neuroscientist, or neurosurgeon so I think this competition would be a good thing to enter, I’m just not sure how to get started. Any advice would be greatly appreciated!
