====== Brain Reference Architecture (BRA) ======
WBAI had released the manual for preparing Brain Reference Architecture (BRA) as the standard notation for guiding the development of brain-inspired software .  BRA is design data based on the mesoscopic anatomical  structure of the brain, providing mainly structural specifications for software as well as functional hypotheses and neural phenomena [1].

A concrete example of BRA data has also been released.  It is a pre-screening version* of the BRA data associated with the article [2] that describes navigation functions of the hippocampal formation. (* The official version will be released after an examination by WBAI.)

BRA data plays a central role in [[BRA-driven development]] that embodies the whole-brain architecture approach promoted by WBAI to construct artificial general intelligence (AGI).
