I am trying to think of a medically related research topic I can use for my English class. I am having trouble thinking of a topic that's debatable.
I was thinking along the lines of "Neurological effects of xxxxxxxxxx" - although it has to be an issue question. BTW I have no medical background, I want a medical topic because I want to learn some neuroscience

(and to confuse my English teacher xD)
So basically what I am asking is: What is a neuroscience issue that is debatable?
