Preamble

Since this document was started, the (not so) persistent identifiers have been changed to be lowercase for all resources. E.g., using lbd:Amygdala won't work anymore; lbd:amygdala will. Likewise lbdo:Brain_Region has been changed to lbd:region. If any of the below queries don't function well, that is likely the problem.

The latest queries can be found in the source code, as part of the SparqlService class.
