Movie 5.

Distinct cell behaviour along the anteroposterior axis of the neural plate. Part 1: Caudal (left) and rostral (right) morphogenesis neural plate morphogenesis from an embryo expressing mem-GFP. Only the caudal neural plate undergoes convergent extension Part 2: Single cell tracking of neuroepithelial cells reveals the presence of cell intercalation at the caudal neural plate (left) and an anterior directed movement of the rostral part of the tissue (right). Time interval = 3 min.
