Preamble

<aside> 🚨 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.
