Network motifs are recurring circuit elements in biological networks. In this chalk-talk, we will discuss the mathematical and experimental analysis of the information processing functions of network motifs. We will analyze several design-principles that cells use for speeding transcription network response-times. We will also discuss the selection of network motifs from an evolutionary perspective.
