Comparison of the inter-region connectivity matrices, renormalized between 0 (white) and 1 (blue). Rows and columns correspond to ABA brain regions. Left: connection matrix from AMBCA (ipsilateral), using ABA’s inter-region connectivity model, with values representing a combination of connection strength and statistical confidence [see Fig. 4a of Oh et al. (2014)]. Middle: same matrix from AMBCA, but symmetrized (connection directionality is ignored, since the NLP models do not extract directionality). Right: connection matrix from the results extracted from the literature (LIT) with values representing the number of extracted connectivity statements, weighted by the estimated precision of each connectivity extractor
