One useful resource I have found using this search is a BBC news article on the role of sleep in memory (http://www.bbc.com/news/health-27695144). The reason I find this useful is because it provides a simple summary for understanding as well as the link to the original article.
Another useful resource I found is Elizabeth Loftus' TedTalk on the reliability of memory (http://www.ted.com/talks/elizabeth_loftus_the_fiction_of_memory). It covers ethical issues as well as CLOA concepts.
