Parallel layers of interneurons in zebrafish larvae.

In two-day-old zebrafish larvae (left), early-born V2a interneurons (purple) in the hindbrain are recruited to circuits to produce rudimentary movements such as escape and struggle. In five-day-old larvae (right), a parallel layer of late-born V2a interneurons (green) is added to the existing circuits to support a range of complex movements, such as spontaneous slow swimming to search for food.
