Movie 2

Two modes of actomyosin contraction in a minimal dynamic cortex.
Two different modes of actomyosin contraction are observed in our experiments under the same experimental conditions: 1) Homogeneous contraction (left panel), and 2) Coarsening (right panel). The addition of myosin is indicated by flashing text and the movie depicts a time period of approximately 6 minutes for two samples. Time is measured from the addition of myosin. Actin intensity is color-coded.
