  1. 1. Chemical circuitry in the visual system of the fruitfly, Drosophila melanogaster

    Författare :Agata Kolodziejczyk; Dick Nässel; Axel Borst; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optic lobe; lamina; neurotransmitters; neuropeptides; tangential neurons; Animal physiology; Zoofysiologi; funktionell zoomorfologi; Functional Zoomorphology;

    Sammanfattning : Signal processing in the visual system is mediated by classic neurotransmission and neuropeptidergic modulatory pathways. In Dipteran insects, especially in the fruitfly Drosophila melanogaster, the morphology of the visual system is very well described. LÄS MER

  3. 2. Motion Vision Processing in Fly Lobula Plate Tangential Cells

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

    Sammanfattning : 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). LÄS MER

  4. 3. Brain-derived neurotrophic factor and endocannabinoid functions in gabaergic interneuron development

    Författare :Paul Berghuis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Formation of the cerebral cortex is controlled by tightly regulated processes: the proliferation and survival decisions of neural progenitors, radial and tangential migration of neuronal precursors, axon guidance and dendritic growth underpinning the formation of synapses. Patterning of the neocortex has been extensively studied and significant progress has been made in understanding the principles of cortical neuronal circuit formation. LÄS MER
