Spontaneous spiral formation occurs when an excitation wave is input to a heterogeneous network of low- and high-light-intensity cells projected onto a light-sensitive Belousov-Zhabotinsky reaction. The range of network conditions where spirals form is increased if two waves are input at critical time intervals. Spirals degenerate to form multiple spirals and spirals trapped within excitable cells. Spiral formation and degeneration is dependent on network excitability, cell size, and network size. Results exhibit parallels with spiral formation in excitable biological systems such as the heart.
当一个激发波输入到投射在光敏感的贝洛索夫-扎博廷斯基反应上的低光强和高光强细胞的异质网络时，会发生自发螺旋形成。如果在临界时间间隔输入两个波，则形成螺旋的网络条件范围会增加。螺旋会退化形成多个螺旋以及被困在可兴奋细胞内的螺旋。螺旋的形成和退化取决于网络兴奋性、细胞大小和网络大小。结果显示出与心脏等可兴奋生物系统中的螺旋形成有相似之处。
