Matched filtering by a photoreceptor membrane

  title={Matched filtering by a photoreceptor membrane},
  author={Simon B. Laughlin},
  journal={Vision Research},
This study demonstrates how phototransduction cascades and membranes tune photoreceptor response dynamics to image quality, and eliminate noise introduced in cell signalling. Intracellular recordings from intact retina confirm that the light-adapted photoreceptors of the crane fly Tipula paludosa (Diptera; Tipulidae) have a slow response, appropriate for their visual ecology. To provide a slow response, the phototransduction cascade's impulse response fails to narrow with light-adaptation… CONTINUE READING
