Abstract

The development of the nervous system in insects, as in most other higher animals, is characterized by the high degree of precision and specificity with which synaptic connectivity is established. Multiple molecular mechanisms are involved in this process. In insects a number of experimental methods and model systems can be used to analyze these mechanisms, and the modular organization of the insect nervous system facilitates this analysis considerably. Well characterized molecular elements involved in axogenesis are the cell-cell adhesion molecules that underlie selective fasciculation. These are cell-surface molecules that are expressed in a regional and dynamic manner on developing axon fascicles. Secreted molecules also appear to be involved in directing axonal navigation. Nonneuronal cells, such as glia, provide cellular and noncellular substrates that are important pathway cues for neuronal outgrowth. Once outgrowing processes reach their general target regions they make synapses with the appropriate postsynaptic cells. The molecular mechanisms that allow growth cones to recognize their correct target cells are essential for neuronal specificity and are being analyzed in neuromuscular and brain interneuron systems of insects. Candidate synaptic recognition molecules with remarkable and highly restricted expression patterns in the developing nervous system have recently been discovered.
