Optimal Hierarchical Modular Topologies for Producing Limited Sustained Activation of Neural Networks (2009, neutral): “n the ratio of connections (e.g. being connected to 10% of all neighbors) largely remains constant across species with different brain sizes (Ringo, 1991; Schüz and Demianenko, 1995; Striedter, 2004; Zhang and Sejnowski, 2000). Moreover, for constant average node degree, the optimal configurations i”

The unreasonable effectiveness of deep learning in artificial intelligence (2020, background): “Interestingly, there are many fewer longrange connections than local connections, which form the white matter of the cortex, but its volume scales as the 5/4 power of the gray matter volume and becomes larger than the volume of the gray matter in large brains (18).”
