This FaithWorld blog isn't actually too bad.
Here's one fairly good article about the contributions that the cognitive sciences make to the study of religion. (To summarize: our brains automatically assume agency even where none exist.)
And another one that speaks fairly well about brain imaging.
However, the site does seem to allow for some weird nebulous religiosity... but I think I can allow it, so long as they keep talking intelligently about my precious braaaains.
