3. Morphologican and functional studies on the Drosophila neuromuscular system during postembryonic stages
Sammanfattning : The nervous system of the fruit fly Drosophila melanogaster has emerged as an excellent model for fundamental neuroscience as well as for biomedical research of human neurological diseases. In this thesis, two aspects of the neuromuscular system have been investigated: the role of the IkB-protein Cactus in the larval neuromuscular junction and the morphology of motor terminals throughout adult life.
