“…9. Here, a spatial representation of an average hierarchy (Reid et al, 2009) derived from the sorting of areas by laminar projection patterns (Felleman and Van Essen, 1991; Hilgetag et al, 2000c) (Fig. 9A) is compared with the structural types of these areas (Fig.…”

Which principles determine the organization of the intricate network formed by nerve fibers that link the primate cerebral cortex? We addressed this issue for the connections of primate visual cortices by systematically analyzing how the existence or absence of connections, their density as well as laminar patterns of projection origins and terminations are correlated with distance, similarity in cortical type as well as neuronal density or laminar thickness of cortical areas. Analyses were based on four extensive compilations of qualitative as well as quantitative data for connections of the primate visual cortical system in macaque monkeys (Felleman and Van Essen, 1991; Barbas, 1986; Barbas and Rempel-Clower, 1997; Barone et al., 2000; Markov et al., 2014). Distance and thickness similarity were not consistently correlated with connection features, but similarity of cortical type, determined by qualitative features of laminar differentiation, or measured quantitatively as the areas' overall neuronal density, was a reliable predictor for the existence of connections between areas. Cortical type similarity was also consistently and closely correlated with characteristic laminar connection profiles: structurally dissimilar areas had origin and termination patterns that were biased to the upper or deep cortical layers, while similar areas showed more bilaminar origins and terminations. These results suggest that patterns of corticocortical connections of primate visual cortices are closely linked to the stratified architecture of the cerebral cortex. In particular, the regularity of laminar projection origins and terminations arises from the structural differences between cortical areas. The observed integration of projections with the intrinsic cortical architecture provides a structural basis for advanced theories of cortical organization and function.

“…Recently, hierarchically modular network topology has been shown to exist in a wide range of biological networks (Ravasz, 2009;Reid et al, 2009) as well as information processing systems like the human brain and complex computer circuits that have been cost-efficiently embedded into physical space .…”

“…The "mosaic organization" of the cortex into specialized regions that become functionally integrated during perception and cognition (Zeki, 1978;Zeki and Shipp, 1988), as well as the idea that large-scale connectivity in the primate brain is structurally (Felleman and Van Essen, 1991) and functionally (Mesulam, 1998) organized into multiple processing streams and forms a hierarchy. More recently, the arrival of quantitative network modeling and analysis Bullmore and Sporns, 2009) has provided welldefined, internally consistent, and methodologically flexible tools with which to characterize and report hierarchy (Reid et al, 2009), informational efficiency (Achard and Bullmore, 2007), small-world connectivity (Sporns and Zwi, 2004;, modularity (Chen et al, 2008;Meunier et al, 2009), and hub structure (Hagmann et al, 2008;Buckner et al, 2009) in brain network data. Topological analyses of brain network have been carried out on MR imaging data as well as on electrophysiological Note the presence of dense pathways between the medial frontal cortex and the PCC as well as lateral parietal cortex, as well as the relative absence of connections between the lateral parietal cortex and the precuneus (see also Van den Heuvel et al, 2009a).…”
