  2. Inhibierende Netzwerke in der äußeren Retina

    Pieper, MarioUniversität Oldenburg

    Horizontalzellen der Retina bilden ein über Gap Junctions gekoppeltes Netzwerk, das für die rezeptiven Felder nachgeschalteter Neurone essentiell ist. Die Horizontalzellen in einer Connexin57-Knockout-Maus, in der die interzellulären Kanäle dieser Zellen fehlen, zeigen verkleinerte rezeptive …

  4. Calcium-dependent mechanisms in the chicken retina

    Tekmen, MerveBiological Sciences2022

    Multiple classes of retinal amacrine cells use L-type Ca2+ channels to mediate synaptic transmission. I have used whole cell voltage clamp recordings from primary cultures of amacrine cells to investigate the regulation of these channels. In this study, I show that inhibiting mitochondrial calcium …

    … by a factor of 10¹⁰. In order to do so, the retina adapts to large, daily changes in natural light intensity by shifting its dynamic range of coding. For example, as morning light intensity increases, the retina implements multiple strategies that result in decreases in overall sensitivity in …

  9. Longitudinal Visualization of Neurodegeneration: Digital Biopsy of the Retina

    Luisi, Jonathan DavidThe University of Texas Medical Branch at Galveston2022

    As treatment for most retinal diseases only begins after vision impairing degeneration is detectable, a better understanding of what changes lead to neurodegeneration is required. Due to the isolated physiology of the eye, the classical markers of inflammation are not detectable in-vivo without an …
