   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

3. 2. The processing of natural images in the visual system

   Författare :Olga Dyakova; Karin Nordström; Dan Larhammar; Eric Warrant; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; natural scenes; image statistics; hoverflies; optomotor response; cSIFE neuron; sleep deprivation;

   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
