Figure 5. A pseudocolor animation of two photoreceptor cells treated with 35 mM K+ and 1 mM Co2+.
A pseudocolor animation of two photoreceptor cells treated with Co2+ as described in the legend to Figure 4, recorded with an emission-ratio frequency of 1/min. In this experiment, cells were recorded under basal conditions for minutes 1-5. The following changes were made to the superfusion medium at the times indicated: 5 min, the extracellular K+ concentration was increased to 35 mM; 10 min, the cells were exposed to 1 mM Co2+ in nominally Ca2+-free salt solution containing 35 mM K+; 21 min, Co2+ was removed and Ca2+ reintroduced in the continued presence of 35 mM K+; 27 min, the extracellular K+ concentration was lowered to basal levels (3.6 mM).
Note that the slide bar at the bottom of the quicktime movie can be used to manually control the flow of the movie. If you do not want to or are unable to view the movie, a representative frame is included below as a still image.
