  1. 1. Motion Vision Processing in Fly Lobula Plate Tangential Cells

    Author : Yu-Jen Lee; Karin Nordström; Holger Kraap; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; hoverflies; EMD; higher order motion; octopamine; cSIFE; figure-ground discrimination; motion vision; lobula plate tangential cells;

    Abstract : Flies are highly visually guided animals. In this thesis, I have used hoverflies as a model for studying motion vision. Flies process motion vision in three visual ganglia: the lamina, the medulla, and the lobula complex. In the posterior part of lobula complex, there are around 60 lobula plate tangential cells (LPTCs). READ MORE

  2. 2. Regulation of insulin signaling and its developmental and functional roles on peptidergic neurons in the Drosophila central nervous system

    Author : Jiangnan Luo; Dick Nässel; Susan Broughton; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Insulin; serotonin; octopamine; insulin receptor; Dimm; neuropeptide; funktionell zoomorfologi; Functional Zoomorphology;

    Abstract : In Drosophila, eight insulin-like peptides (DILP1-8) are produced and secreted in different locations. They regulate many aspects of development and physiology, such as organism growth, metabolic homeostasis, reproduction, stress resistance and life span. READ MORE

  3. 3. The Molecular Mechanism of Aggression and Feeding Behaviour in Drosophila melanogaster

    Author : Philip Goergen; Helgi Schiöth; Michael Williams; Simon Tuck; Uppsala universitet; []
    Keywords : Drosophila; aggression; obesity; homeostasis;

    Abstract : Obesity is a complex disorder which has become a growing health concern. Twin studies have demonstrated a strong genetic component to the development of obesity and genome wide association studies have identified several genetic loci associated with it. However, most of these loci are still poorly understood in a functional context. READ MORE
