   Sammanfattning : Any image can be described in terms of its statistics (i.e. quantitative parameters calculated from the image, for example RMS-contrast, the skewness of image brightness distribution, and slope constant of an average amplitude spectrum). LÄS MER

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

   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
