Formation of precise neural circuits is essential for perception and behavior of organisms. As a model system to study mechanisms of neural circuit development&s_comma; we are using the olfactory system of Drosophila. The olfactory system demonstrates a dramatic example of precise neural circuits&s_comma; with single classes of olfactory receptor neuron axons and single classes of second order projection neuron dendrites forming one class to one class connections at the antennal lobe&s_comma; the first olfactory relay station in the brain. This organization is conserved from flies to mammals. We are studying cellular and molecular mechanisms of dendritic targeting of projection neurons&s_comma; as well as axon targeting of olfactory receptor neurons.
