The motive forces underlying convergence and internalisation of the teleost neural plate remain unknown. To help understand this crucial morphogenetic movement we have analysed collective and individual cell behaviours at the superficial surface of the neural plate. Convergence to the midline does not rely on mediolateral cell intercalation, it is characterised by oscillatory contractile behaviours, a punctate distribution of Cdh2 and medially polarised actin-rich protrusions at the surface of the neural plate. Additionally, we characterise and discuss the intimate relationship and dynamic cell surfaces between the motile neural plate and the stationary overlying non-neural enveloping layer.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
