Imaging sequence of calcium waves from 95% epiboly to 12-somite state. Note that bidirectional waves predominate throughout this sequence. The waves in the latter two thirds of the sequence originate ...

10 Tailbud pulses over 105 min at 8-12 somite stages. This is the latter part of the 95% epiboly to 12-somite sequence flipped vertically for clearer orientation. The movie represents a 120-sec int...
