Abstract
We study the order-chaos phase transition in random Boolean networks (RBNs), which have been used as models of gene regulatory networks. In particular we seek to characterise the phase diagram in information-theoretic terms, focussing on the effect of the control parameters (activity level and connectivity). Fisher information, which measures how much system dynamics reveal about its parameters, offers a natural interpretation of the phase diagram in RBNs. We report that this measure is maximised near the critical state in the order-chaos phase transitions in RBNs, since this is the region where the system is most sensitive to its parameters. Furthermore, we use this study of RBNs to clarify the relationship between Shannon and Fisher information measures.
