Biased excitable networks: how cells direct motion in response to gradients

Highlights ► The actin cytoskeleton in motile cells behaves as an excitable medium. ► This excitable behavior can account for the spontaneous migration of cells. ► Recent models show how chemoattractant signaling biases the site of excitability to direct cells. ► We demonstrate how persistence and p...
