We show that models for orientation map formation, which invoke convolution in the dynamic equation, are in fact invoking non-local reaction diffusion. In the early stages of development, it is unlikely that non-local interactions take place. We present a non-linear reaction diffusion model based on near neighbor interaction for formation of orientation map. Besides capturing all the essential topological qualities of experimental orientation, our model also deals with the interspecies variations in the orientation map.
