Imaging sequence from 95% epiboly to 12-somite stage

This sequence covers 5.25 h of development.

  • The movie represents a 40-sec integration window moving in 15-sec steps, running at 150x real time.
  • Note that bidirectional waves predominate throughout this sequence. The waves in the latter two thirds of the sequence originate near the tailbud region and are referred to here as "tailbud pulses".
