For the case studies, check out the contents of the journal links below (I know AN has some).  Here are links to the Discover Magazine articles (search for "Mind and Brain" as topic) and Scientific American (which has fewer).  Also check out The Clinical Neuropsychologist and JCEN abstracts and the tables of contents for JINS (I have the journals in my office).

Note - Some of these journals offer all articles but only for a limited time; others are free full text after 1-2 years.  If you can't access a recent article, try an older volume to see if those are accessible...
