Figure 5From: An optimally evolved connective ratio of neural networks that maximizes the occurrence of synchronized bursting behaviorIllustration of feedback loops and APFLs. (a) An example network composed of five different feedback loops. An interaction between nodes is represented by arrows to denote excitatory regulation and blunt lines for inhibitory regulation. The sub-networks colored in red denote the two APFL motifs. (b) Five feedback loops (FBL) contained in the network shown in (a).Back to article page
