摘要: The collective behaviors of excitable system in heterogeneous media are discussed. Due to the heterogeneity on diffusion and other properties media, spiral wave would drift over its stability is also be affected. different for dense sparse waves because their core properties. Moreover we have found that spatial inhomogeneities could destabilize wave. It cause stable meandering or even breakup. Several cases been investigated including effects caused by fiber rotation cardiac tissue. meaning these results neuro-dynamics brain cognitive behavior discussed
