Voltage dependent potassium currents were recorded using the wholecell mode of the patch-clamp technique for the first time from endfeet of Muller cells dissociated from the frog retina. Recordings from intact cells and isolated endfeet indicate that the inward rectifier potassium channel is the dom

The reduction in amplitude of the a-wave of the frog ERGs in response to ~ight at seven different intensities recorded from isolated frog retinas (Rana catesbiana) caused by ouabain (10 -5 M) was partially prevented dose-dependently by the insulin pre-treatment (between 6.6 x 10 -8 and 6.6 x 10 -5 M
Mu ยจller (radial glial) cells span the retina from the outer to the inner limiting membranes. They are the only glial cells found in the amphibian retina. The thickness of the frog (Rana pipiens) retina decreases by a factor of about four from the center to the periphery. Thus, Mu ยจller cells were i
