Oscillatory media properties' influence on speed of excitation propogation.

We study behavior of locally diffusively coupled Bonhoeffer - Van der Pol (BvdP) oscillators. We investigate how the properties of cells, more concretely, individual frequencies influence on the excitation propogation through the 1D and 2D media. Speed of excitation propogation depends on the frequency mismatch between individual cells and the rhythm, which synchronises
the media. Qualitative and quantitative results, describing this dependence are observed in numerical simulations and explained.
