General introduction How are flexible and robust animal behaviors orchestrated by the nervous system? Different forms of this general question have occupied neuroscientists for decades. Great strides have been made toward describing the elements of nervous system development, structure, and function. Our next challenge is to examine how behavior emerges from the interactions among genetic, cellular, cell-system, and organ-system levels of organization. My laboratory studies these interactions in a powerful model system ? the fruit fly Drosophila melanogaster. Whereas research with Drosophila is most often focused within the molecular-genetic spectrum of modern biology, this animal also shows remarkable behavioral performance, making its living navigating vast distances through complex visual landscapes in search of the source of an attractive odor. A fly?s sophisticated navigation capabilities emerge from the fusion of multiple sensory modalities and transformation of a robust motor code. By combining the rapidly expanding toolkit of fruit fly molecular genetics with live imaging and 'virtual reality' behavioral techniques, we hope to reveal the functional mechanisms and structural circuits with which the fly brain coordinates the biomechanics and dynamics of complex sensory behavior. The results of this cross-disciplinary approach could have broad impact on our understanding of the general principles of sensory fusion and sensory-motor integration common among animal taxa, and also motivate specialized technical advances in bio-inspired robotic devices.
