The widespread presence of networked systems in technical applications as well as in the business world makes network research useful for future applications in information systems (IS) research. Research into networks means not just analyzing the topology of networks, but also examining the dynamics of the processes that take place in them. Research into diffusion processes in networks has bee...

When a simple excitable system is continuously stimulated by a Poissonian external source, the response function (mean activity versus stimulus rate) generally shows a linear saturating shape. This is experimentally verified in some classes of sensory neurons, which accordingly present a small dynamic range (defined as the interval of stimulus intensity which can be appropriately coded by the m...
