Loop, Resonate, and Accelerate! (IMAGE) University of Freiburg Caption Schematic depiction of a network of networks with one resonance pair: 200 excitatory neurons (E) in each network, including 70 projecting neurons (P) and 50 inhibitory neurons (I), have random, homogenous, sparsely returning connectivity. EE connectivity - shown with blue arrows -- sparsely links several networks in a feedforward-way. The red arrow from Network 2 to Network 1 shows sparse, random feedback loops from the second to the first EI network, which designates both networks as a resonance pair here.
