Each button below takes you to a page with a summary of the topic from my perspective; links within this summary text are usually to high quality articles, but not to the peer-reviewed scientific literature itself. At the bottom of each page are links to a selection of the peer-reviewed literature, often review articles which will contain many references to additional research articles on the topic. I tried to link to the full text of articles when possible, but when that's behind a paywall, I link to an abstract, usually on PubMed. If you want the full text of an article that isn't freely available, many authors will send you a pdf of their papers if you email them to ask. Here are some hints if you're new to this, but want to do more digging into the scientific literature on your own. And if you want to suggest another advanced topic, send us an email!
