Topic is how does brain damage correlate to criminal behaviors and actions. Go into detial what part of the brain is affected its main function. 
you should follow an overall structure where you broadly introduce the topic, then review your literature (at least 5 peer-reviewed empirical research articles), and finally conclude with a synthesis of the information you presented.
When writing about the articles you should be focusing on the FINDINGS of the study not the RATIONALE. What that means is you should be citing information from the results/discussion, as opposed to the introduction. Everything should be put into your own words as well (quoting is not allowed!). There should be a logical flow throughout your paper – it is best to cite more than 1 article per paragraph and make connections between the findings to support a statement or conclusion as opposed to dedicated an entire paragraph to each article individually.
