We propose a model for the formation of patterns in the visual cortex. The dynamical units of the models are Kuramoto phase oscillators that interact through a complex network structure embedded in two dimensions. In this way the strtength of the interactions takes into account the geographical distance between units. We show that for different parametes, clustered or striped patterns emerge. Using the structure factor as an order parameter we are able to quantitatively characterize these patterns and present a phase diagram. Finally, we show that the models is able to reproduce patterns with cardinal preference, as observed in ferrets.
