The effects of excitatory amino acids on the membrane current of isolated retinal glial cells (Müller cells) were investigated using whole-cell patch clamping. 2. L-Glutamate evoked an inward current at membrane potentials between -140 and +50 mV. The current was larger at more negative potentials. 3. The glutamate-evoked current was activated by external cations with relative efficacies: Na+ much greater than Li+ greater than K+ greater than Cs+, choline. It was activated by internal cations… CONTINUE READING
