Spiral wave

Spiral waves are travelling waves that rotate outward from a center in a spiral. They are a feature of many excitable media. Spiral waves have been observed in various biological systems[1][2] including systems such as heart ventricular fibrillation,[3] retinal spreading depression,[4] Xenopus oocyte calcium waves,[5] and glial calcium waves in cortical tissue culture.[6]
