 ====== Brain Information Flow Diagram (BIF) ======
-WBAI proposes the Brain Information Flow Diagram (BIF) as a format for describing and sharing the whole brain architecture (cf. information flow diagram).
+WBAI proposes the Brain Information Flow Diagram (BIF) as a format for describing and sharing the whole brain architecture (cf. [[https://en.wikipedia.org/wiki/Information_flow_diagram|information flow diagram]]).

 ==== Overview ====
 BIF is composed of Circuits and Connections between them.
-A Circuit corresponds to a population of neurons, an organ in the brain such as the hippocampus, or a circuit consisting of brain organs, to perform a certain function.

 ==== The BIF Ontology ====
-BIF elements are defined by an ontology with the following classes and properties.
+BIF elements are defined by an [[https://en.wikipedia.org/wiki/Ontology_(information_science)|ontology]] with the following classes and properties.\\
-Circuits and Connections are normally defined as classes rather than instances.
