My professor wants me to write a literature review on the topic of the Gut-Brain

My professor wants me to write a literature review on the topic of the Gut-Brain Axis Influencing Brain Morphology in relation to the gut microbiome. I want you to include research from
reputable medical journals that prove that gut microbiome can alter brain morphology. Use journals like Nature and Frontiers and also papers on pubmed and google scholar. the more recent the citations the better. I will attach a document that my professor told me to follow the same outline of and the way of writing too. Try to make it similar to the document attached but not too similar because of plagiarism purposes. The citation style sould be harvard style, and add a references page in the end. 
here are some links that can be use for citation:
