An example core network from a final population, for τ = 3 in a static environment. The core network includes seven intermediate nodes, an input node, and an output node. The network is dense, and representative of the core networks found in the populations. The full networks contain an average of 15 nodes, usually of similar connectivity. The networks consist of parallel and nested feedback loops, allowing for the creation of different oscillatory output signals in response to different input signals.
