Release of the Preparation Manual and a Concrete Example for Brain Reference Architecture (BRA) Data

WBAI  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.)

  • Hippocampal formation BRA data (pre-screening version):  HPF.bra

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).

In the near future, accumulating BRA data for the entire brain in line with the spirit of CUDOS (*1) will made possible to promote the open development of AGI inspired by the brain.  We believe that this will contribute to the realization of our vision of  “creating a world in which AI exists in harmony with humanity.”

*1 CUDOS is an acronym for Communalism, Universalism, Disinterestedness, and Organized Skepticism, which are the ethos of the scientific community advocated by R. K. Merton.
