title: From egg to action.
abstract: The development of the neural control circuitry underlying different patterns of behavior is rapidly expanding area of interest in neuroscience. New important insights have been gained over the last few years at different molecular, cellular, network, and behavioral levels. Based primarily on the issues presented in the review articles in this issue, I have added some reflections as to what I find most challenging and important.
