The CM. (A) The expression pattern of the neurons A to G are summarized in the label expression matrix $X$. (B) The operators connecting the labels can be summarized in the organizing rule matrix $O$. (C) In the CM, the brain connectome ($B$) emerges from $O$ and $X$ through the CM Eq. 1. Each time two labels are connected in $O$, the corresponding neurons in $X$ can form synapses. Only nonzero elements are shown in the matrices.
