Help with paper topic

[David J. Kanter]

I’m really stuck for a topic.

	I work full-time, and in the hopes of attending medical 
school in the next couple of years, I’m taking some night classes 
--- one of these classes is biology.
	In this class, we have to write a paper similar to a 
research grant application --- come up with some unresolved issue 
in biology or medicine, and write a proposal on how we’d go about 
resolving the issue.
	I find neuroscience fascinating, and would like to write 
my paper on a neuroscience topic, but with essentially no 
knowledge about this field, I have no idea where to begin picking 
a topic.
Does anyone know of an unresolved issue a novice like me could 
investigate?

	Thanks,
	Dave
