Pulsed Interaction Signals as a Route to Biological Pattern Formation

We identify a mechanism for biological spatial pattern formation arising when the signals that mediate interactions between individuals in a population have
pulsed character. Our general population-signal framework shows that while for a slow signal-dynamics limit no pattern formation is observed for any values
of the model parameters, for a fast limit, on the contrary, pattern formation can occur. Furthermore, at these limits, our framework reduces, respectively,
to reaction-diffusion and spatially nonlocal models, thus bridging these approaches.
