Figure 9. Benzolamide does not increase the feedback-induced inward currents in cones in the isolated goldfish retina.A, Feedback-responses elicited by a 500 ms full-field stimulus (I = 0 log) delivered in the presence of a 20 µm spot of light (I = 0 log) centered on a cone clamped at −43 mV. Current responses are shown in control (top), after application of 500 µM benzolemide (middle), and after washout (bottom). B. Feedback induced shift of the Ca-current of a cone in 100 µm benzolamide. 30 µM kainate shifts the Ca2+-current to more positive potentials, whereas a subsequent application of 50 µM DNQX shifts the Ca2+-current to more negative potentials. The difference of the half activation in kainate and in DNQX is 7.0±1.6 mV (n = 6). Image published in: Fahrenfort I et al. (2009) Image downloaded from an Open Access article in PubMed Central.
