Spiral wave

Last updated

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] Dictyostelium cAMP waves, [4] retinal spreading depression, [5] Xenopus oocyte calcium waves, [6] and glial calcium waves in cortical tissue culture.
