Abstract
Motor neuron differentiation has been studied intensively in both invertebrates and vertebrates in recent years. These studies have led to the identification of several key regulatory genes acting to generate motor neurons and to specify their subclass identities. By comparing findings from Caenorhabditis elegans, Drosophila and vertebrate model systems, it is apparent that both evolutionarily conserved and non-conserved mechanisms are used.
