摘要
Background: 網絡 motifs are recurrent interaction patterns, which are significantly more often encountered in 生物 interaction graphs than expected from random nets. Their existence raises questions concerning their 湧現 and functional capacities. In this context, it has been shown that feed forward loops (FFL) composed of three genes are capable of processing external signals by responding in a very specific, robust manner, either accelerating or delaying responses. Early studies suggested a one-to-one mapping between topology and dynamics but such view has been repeatedly questioned. The FFL's function has been attributed to this specific response. A general response analysis is difficult, because one is dealing with the dynamical trajectory of a system towards a new regime in response to exte
