  • Title: Observations on rod coupling in the isolated retina of Bufo marinus.
    Author: Griff ER, Pinto LH.
    Journal: Vision Res; 1984; 24(2):149-57. PubMed ID: 6424326.
    Abstract:
    Rod coupling was studied in the superfused isolated retina of Bufo marinus. Pairs of interacting rods were simultaneously impaled; current injected into one rod caused a current-induced potential in the second rod. Current-induced potentials and input resistance were monitored while changing the superfusate. Interactions were not reduced by removing extracellular Na+ or Cl-, indicating that these conductances do not mediate coupling. Interactions were not eliminated by altering extracellular Ca2+ or decreasing intracellular pH; the interactions are thus resistant to treatments that uncouple cels in other systems.
