The common fruit fly - Drosophila melanogaster - has been the subject of genetics research since the early twentieth century. The complete genomic sequence of Drosophila was published in 2000 and it is still the model organism par excellence for the experimental study of biological phenomena and processes. It is also by far the best model for studying gene function in mammals, including humans. Presenting state-of-the-art studies on the behaviour of Drosophila, this volume discusses normal and pathological models of neurobehavioral disorders and encompasses the specialised methods that have been used, from anatomical, histological, immunohistological and neurophysiological to genomic, genetic and behavioural assays. A comprehensive and thorough reference, this volume is a valuable resource for students and researchers alike across several disciplines of life sciences, including behavioral genetics, neurogenetics, behavioral neuroscience, molecular biology, evolutionary biology and population biology.
